from one of my other posts
many things have changed
especially for smaller suv's and trucks that do not require LR E tires.
and you can get mud terrains, higher load indexes are ok, speed ratings on the big wheeling jeep are not usually a problem(unless you started with the srt8 maybe), and we can go to bigger sizes.
Costco has had some policy changes that make buying bigger tires for jeeps much easier.
their are some restrictions
1. they can't rub(at least while on flat ground, hard lock to hard lock, or be very very close to rubbing)
if they do rub with articulation, the tires are yours anyway, which most people are good with, and will mod the jeep to get them not to.
2. we have to be able to inflate to the placecard air pressure(even if you would actually run a little higher or lower)
3. the tires have to be able to hold the same if not more weight than the stock tires.
4.they can not be too wide or narrow for the rim.
costco can usually get companies to make products specifically for them, but they will usually be better(that is what they try for)
I will call on the battery thing though.
I know all our batteries are from johnson controls or something like that.
I will try to call on that on monday when the buyers are in.
but I just got this back from the people at optima batteries
"Hello Steven
An Optima sold at Costco is the same product that could be purchased at any other retail location. Their inventory may vary depending on what group sizes they carry but the overall product is the same.
Thank you,
