Title: Tire Questions
Post by: 1988 Cherokee on February 24, 2010, 03:15:58 PM
I got some stupid questions to ask.

How can I tell how much tread is on each tire?

Is it ok to have 3 of the same brand of tire, with 1 different brand but same style (All Terrain). And 2 of the 3 same brand of tire are brand new?

What about same situation as above but instead of 2 brand new tires, I get another 2 used but same brand having 3 tires same brand and one not, then having all 4 tires different tread but all above a certain percentage, lets say 50 or 60%?

I have to lay off inhaling the paint fumes  :-[

The actual size of a given tire will differ between manufacturers. For this reason, I wouldn't suggest that you run a different tire on each side of the axle. Now....if you wanted to run two different sets of tires front/rear, then I don't see a problem so long as they're the same size (ie: 31x10.5x15).

Only lay off the paint fumes if you're starting to see gazoo!!

1. there is a tool that measures the depth of tread and you compare that to the original depth of the tread to know what % you have left.  all tires have a wear inidicator in between the lugs somewhere that tells you when to change (approx 10%).

2. It's not ok to have different brands all over or on different axles at least.  different tracking or weight or whatever can cause problems... prob 100 reasons why not.

3 if you have new tires they should be on the same axle and i recommend them on the front for braking and steering purposes, others say back for unknown reasons.

highly recommend same tire size and brand all around on 4wd vehicles. if off road only then you could get away with one brand front and one brand rear. but on a street driven vehicle i can only suggest 4 of the same brand. rotating your tires will keep tread wear to a minimum. i prefer better tires at the back on rwd or 4wd for traction purposes. and it could be argued that if the rears have less tread then they could cause a vehicle to loose rear traction when brake lock-up occurs... sounds like it came right out of a text book.

I'm with Eric on this one.  I've also heard some people recommend not doing the 5 tire rotation because the difference in height with the 5th.  I'd recommend all same tire and all same tread depth.  No mix-match.  Different brand tires and different wear bepths is how transfer cases blow up (just ask my boss).

ideally all four tire should be the same,
don't mix tires on an axle,
new tires should always go on the back, all vehicle, 4wd rwd fwd, if you are not sure why, check all manufacturer's and gov't tire related web sites.

tire depth guages are cheap and are available at all auto parts store.

I've always believed that anything less than 4 same tires is a compromise, but I'm not here to disagree.
My point is if you check history the "manufacturers" in North America insisted bias ply tires were as good as radial tires because they had too high a tooling cost investment in bias ply tires.  They stalled long enough to get their investment paid for. ( approx 10 years)
So much for the credibility of manufacturers.

I asked this question because I bought one used BFG AT KO and one used Goodyear Wrangler AT with good tread depth, no knicks or scars.

You have 2 good spare tires.
Title: Re: Tire Questions
Post by: Zombie on February 24, 2010, 11:17:44 PM
doing so is not advised as different tires are not all created equal.
neither in size, traction or handling characteristics.

the best solution is to have all 5 tires the same and rotate the spare in at every rotation.
I would hope that the tires would not differ more than 2-3/32nds of an inch and there should not be too many problems.
on top of that, if you do happen to have a tire damaged, the spare will match and you will be able to continue to use the other tires and have a new(or used spare that would not be put into the rotation pattern (as the others will likely be too far worn to just have one new tire.

this is the ideal situation. many people will not have a matching spare, and that just means that if one tire is damaged and they are not almost new, the others could be to far worn and a whole new set may be required.

this may be a good debate as many old timers may say it does not make a difference, but I don't buy that.

try to find matching tires with similar tread depth

That is exactly what I am going to do, just get them all the same size with similar tread depth.

these are 2 very different tires. and if it truly is a goodyear AT then i would say its at least 10-15 years old. the GY AT was discontinued in 1998-2000 ish. if its the GY at/s the nthats much newer, but still way different then the bfg. if you're trying to save a few bucks you're going to loose out in performance and long term drivetrain issues.

are the retread tires anygood, those are like $75-$85 per tire for all terrain.

http://www.treadwright.com/shopnow/entity/tabid/60/entityname/category/categoryid/7/sename/31-10.5R15.aspx

I wouldnt mind buying all 4 retreads for around $300, but to drop $200 to $250 a hit at these tire stores is steep. I guess I will go around to the used tire stores tomorrow around chinook there and see whats available.

what I want to know is how they can retread tires using other companies tire treads?

you would think there would be some issues there.

This is only my personal opinion based on my very limited knowledge of tires but I have always been told not to use them.   Maybe on a trailer... maybe... not very likely though.  It have to be the only tire available and my kids would have to be on fire...

Tires are probably one of the most important things on your vehicle.  I can't see any benefit to not coughing up the price for tires. 

If your really on a budget, try to swing a deal on some slightly used tires .   Tires are to important. Try to save money else where on your vehicle.   don't cheap out on the rubber.

I'm with Kev on this one.

I would not put a retread on a Jeep. I MIGHT be willing to put them on a tandem-axle trailer...maybe.

Retreads are a little sketchy when it comes to commercial use...and that is with specific regulation controlling how they're used on large trucks. When there are 18 wheels, the need is there to regulate how and when re-treads are done.

We only have four wheels....and there are no regulations around light vehicle retreads that I know of.

Do not used retread!.... there is a reason why the truckers ONLY put them on the trailers. It's a safety thing.

These tires gets hot and will blow up on you... it will DESTROY whatever is around the tire..Including the Jeep. I knew a guy that had them on a small Ford Ranger pickup truck... He learned the hard way not to used them when part of his box got blown away by his retread.



Ok ...I understand that it is a expensive sport... DO NOT CHEAP OUT ON SAFETY! .... Cheap out on fender flair, head lights, roof rack not on tires dude!... that's the only think keeping you on the road.

Buy a quality tire,... save up, pay the $$ and you will save at the long run.

Joel here on the site runs Kralers. They are expensive tires but he had them for ...I don't know ...6 years maybe?.. They still look new. I'm sure he will still have them in 6 +  years unless he gets tired of them.


You live, you learn,... I have learned the hard way. Buy Quality parts!

That's my 2cents

X2 Dom;    also its illegal to use a retread on the steering axle of  a big truck, that in itself tells a story

www.kijiji.ca

search each independently:

30x9.5
31x10.5
jeep wheels tires
jeep rims tires
jeep 15

There are good deals out there, really good deals.  JohnnyC currently has (or maybe had) 4 31x10.5's brand new for 600$  I have seen tires on wheels on kijiji in good shape (ie 50-60%) for 3-400 for the entire package.

dont ever cheap out on rubber, but it is okay to be thrifty if you know what I mean.  ( I am a wheel/tire whore I love buying and selling that stuff)

not 100% of the shape of the tires but you get the idea..

I have to get these tires out of the back of my truck and onto the jeep itself, but I want to wait for a good deal on used tires to come along. Free up some space in the back and maybe go with a custom roof container for parts, tools and supplies.

Out of curiousity what are the generally prefered tires for Jeeps? are they the Wrangler Terrain 31x10.5R15s? I've seen those mentioned a few places. My TJ I picked up last week has some Michelin LTX all seasons (30x9.5R15) on them which I'll be using for now since they are in good condition but I just want to know what to look for in case a good deal comes up down the road.

Are there certain tires to watch out for (not to buy) (please don't say Michlin LTXs... ha!)

I heard canadian tires are bad, but I dont know through personal expirience. I would just go with the major brands, except Bridgestone/Firestone because they had a huge recall years ago and my good wrench head buddy says stay away from them.

Those LTX tires are good for longevity, not so good for off road traction.

I am very Toyo Biased, the M/T's have great longevity and off road traction, but they are very heavy, worse mileage, etc.  I have heard good things about the Cooper light truck tires. 

Used tires are for sale often in this forum, and if you wanted to try out different tires you could find what you like that way.  IE a used set of bfg a/t's in similar size with about 50% may only cost you 2-300 here depending on the seller.

At the end of the day, if the tires take you where you want/need to go, they are perfect for your application.

they are not.
 but just like always you get what you pay for.  The wrangler territory's are a good AT, and when on sale are a great deal. CT can get any bfg, goodyear, michelin and many others at a competive price, just ask .

fwiw there are many good used tires out there, but you have to remember they aren't going to be given away for cheap:  and if you're looking for something specific and someone has it, don't mess around; grab them, specially if they are a good deal. 

keep in mind there are two reasons why people sell tires;
1: they are sick of mud terrains and go back to a different brand OR they upgrade from AT to MT, OR a bigger size;  essentially this is a personal choice: example, i have jumped from Iroks to MTs etc nothing wrong with the old tires; just bored of them.
2: old owners 'bought new ones' in a similar size tread pattern.  but why?  well look at them; uneven treadwear, different % left on tires, damage etc.  these you can get cheap if thats what you want.    but if all 4 tires aren't identical, i'd run.   example; the tires i had on my old Grand, i could have sold on kijiji, but i have morals, and gave them away for a bottle of rum, with the promise they would be used only for the rims. why? because i knew they were junk.



my .02 on Canadian tire brands; don't bother.  if you want to order BFGs through then fine, but as ANYONE who runs a Canadian Tire brand 'roughrider' (like pook, and me unfortunately) and they can't wait to get these POS off their jeeps.  i've NOTHING good to say about canadian tire brands.  i'm sure the territory's will be fine for a few years; just hope you wear them out before they fall apart.

the canadian tire rough riders were not the best but they were good in the mud and got me out wheeling giving me an oportunity to see what i really wanted to run. they were bad on the highway and ate the gasmilage but in the end i had fun with them. and like johnny says when i get rid of them i will practically give them away so some one else can use them and find out what they are looking for and have some fun.

it is true you get what you pay for.

You can run almost anything you like, re-treads, bias/radial mix etc, JUST KEEP IT OFF THE ROAD!!!! Ooff roading...as long as it isn't flat it's good. Please don't run so-so tires on the highway - or keep it under 50 km/h, the person you kill might not be you.
