Dilema with Tires 33"/ speedometer

[Anton]

SO I got my new Rustys 3.25" basic lift and have some other upgrades, now i want tires, i want to get 33" tires.

I have been reading and asking but still not fully happy with some answers.

i saw that i need to change my gears when i put bigger tires and do something with the axles. I am not a hard core off roader, most of time it is on the road (my only wheels) and i really do not want to get in to hard big upgrades. maby when i would know how to work on my rig beter and more time, lol money too.

So do i really need to change my gears if i get 33" tires, and if i don't is it bad for my jeep or i just need to take it easy when i go wheeling?. How bad would day by day drive would be if i do not change it?  


I go 3 times a year on non hard trails. L would love to go to all the jeep 101 and open family trips.  Other idea is to get small rim with smaller then 18" (stock) and get the 33", would that make any difference for the gearing problem?

Thanks
Anton

Yeah, welcome to my world

There are only a couple things that enable to justify spending money the jeep

1. I intend to keep the Jeep for a very long time
2. I intend to wheel it regularly
3. I enjoy the build process and learn tons while doing it

If you drive the jeep everyday gears become worth it particularly when you have a 3.07 ratio. 33" tires for occasional wheeling don't make enough sense to me, I'd stick with 31's and enjoy it. If you have more time to go and wheel then 33 would be worth it.

The 18" idea won't do anything

just saw you have a JK

33s will probalby be fine; stock you have 32ss............  you will likely wear out front end parts a little faster like hubs and stuff though.


good luck with it!

[Anton]

hubs and stuff though?

all that in the gears or around the wheels? if i put spacers would that help or only give me 100% clearance for not rubbing

[JackstandJohnny]

hubs and stuff would refer to ball joints, ad wheel bearings.  typically bigger tires will reduce these parts' lifespan.

wheel spacers will negatively affect that lifespan of hubs with bigger tires. 


gears are in the diffs.  if you are just stepping up to a 33" tire stock should be just fine.

So i looked around found this

Goodyear Wrangler MT/R with Kevlar and the Duratrac comes for my 18" rim: LT 275/70/R18 = 33.4" tire and LT 275/65/R18= 32.1 and 

1. LT 275/70/R18= 33.4" Tire
2. LT 275/65/R18= 32.1" Tire
3. LT 295/65/R18= 33.1" Tire

Canadian tire have the Territory tire with the sizes 1 and 2 stated above. Now witch size would work the best for me?

[specialk]

Between the Kevlars and Duratracs, do the Kevlars.

[w squared]

Between the Kevlars and Duratracs, do the Kevlars.

If you want a real M/T tire. If you want an AT that can handle some mud and does well in the snow, the Duratracs are a good buy.


Right Kev?....

with the lift you mentioned, I think 33" will look way too small, and I'd go for 35s. I have t 2.5 teraflex coil lift and 33s look good, but would not go any higher without going 35s IMHO. I have duratracs and have been really happy with them on my sahara 18" wheels (one of the problems with the sahara wheels is that they won't really take wide tires and if you want nice fat ones, you will need some new wheels).

A lot of the guys at work run duratracs year round on their pickups...They all love em...  That says a lot when you drive 6,000 km a month both on highway and lease/bush/ice roads.

[Anton]

Ok, then betwen the 33.4 and 33.1" now with ur ex and knowledge would the sizes that I stated above will fit my rims? I would not go with 35 too big, I seen sahara lifted 3 " with stock tires and rim and I liked it. So ya 33 would be by bigest size.

SO i fund the tire on tire rack. Wrangler DuraTrac is that size is good fit? 275/70R18

[Bone206]

I'm running 275/70/18 on the OEM Sahara rims and they fit nicely. I air them down to 12 psi and have had no problems with bead issues etc. They are great year round tires.

[Bone206]

oh yeah, and I'm on she factory 3.73 gears and have no problems with it.

[Anton]

Well finaly i feel beter now, that was alot of info and great one!!!!! thank you so much guys!!!!!

you air them down 12 Psi when you off road right?

I don't know if you will find a set psi for off roading, as it all depends on the terrain your facing. I was told and have found that a few psi makes a HUGE difference. I was wheeling in the snow a month ago, at 12 psi, and my traction was Ok... I was wheeling a few days ago in the snow at 9 psi, and my traction was amazing. I was climbing hills that at 12 psi I would have struggled to make. I think it depends more on the conditions as to what psi you should run. On a good tire, you should be fine down to around 8 or 9, possibly even lower, but then of course you run the risk of losing a bead. If your wheeling with sensible people however, re-seating that bead is not a huge issue on the trail, if you have the right gear with you, and the knowledge / patience to do it safely.
