The OFFICIAL IFS "What size tire will fit" thread
#501
Chevy wheels??
I have an 89 4runner with 235/75-15s. I want to use some Chevy/GMC wheels and was wondering if anyone was had any success with 17,18, or 20" wheels?? Looking at a comparison charts none look to be much different than some 32.11.50-15s. I don't have any lift, yet. I think my biggest concern is the backspacing and rubbing. Can anyone please tell me what I can get away with both diameter and width? 
Thanks for any advice.

I have a 1991 pickup 2wd. Add a leaf in the back which gave me about 2 inches and ball joint spacers up front with my torsion bars slightly cranked. I'd say I gain about 2 inches. Anyone know what size tires I can fit without rubbing on 15" wheels. I'm stuck between 205/75 and 215/75 or can I go slightly bigger?

I put 215/75 15 on stock jeep rims on my daughters 2wd with no lift and have no issues.

New to the forum and trucks, I've a curiosity and found this thread. I've an '88 22r 2WD, 4spd manual, very stock..currently running 205/65/15, doesn't rub and it looks like there's still some space around the fender wells to go a bit bigger, I'm just uncertain as to how much bigger I could go without rubbing. I'm open to suggestions and insights.

1991 toyota 4x4 pickup
I'm about to open an account at les schwab and buy new wheels and tires....I'm stock height right now with 265/70/17 tires and I want to get 32/11.5/15 on some offset wheels so my tires will stick out more...i want a stanced looked...how wide of wheels should I buy to get that look? And on top of that depending on the wheels that I get, will this size tire even work?

This is more of a 'what tires can be fitted to what rims' question, rather than "what won't rub on the truck' type of post.
I'm writing to try to find out if 10.5" wide tires will fit on stock rims before I go to a tire shop. I just got a set of stock rims because the bullethole rims I got with the tires I want to use has clearance issues at the rim. Is there a maximum width for the stock rims? They currently have 9.5 on them, best as I can tell.

No might be what your tire shop says, if they go by some fitment chart or by what the tire mfg. recommends. So best to check the tire mfg. web site for the exact tire you are looking at and see what they for min. and max. rim width. And might be worth checking with the tire shop to see what they will mount. I've found shops that will mount up anything you bring in and others that only go by the "book".

I have a few backwoods tire shops that will mount whatever I bring them. Unfortunately, BF Goodrich's website says they don't currently make tires fitting '83 or older, which I'm pretty sure is just the website's fault for not being a real live tire expert.
The real question here is, are there any negative consequences of running wide-ass tires on stock rims that usually only have much narrower ones mounted on them? You seem to have answered 'no', by stating that you run, I think, 10.5" or wider tires on stock rims with no problems, and since most of the 15" tires and wheels are interchangeable by that standard, I should be ok? Like I said, but maybe a little more detail: the stock rims have some pretty narrow looking "30x9.50R15" tires, and the rims that have bad clearance with my front hubs have "31x10.50R15LT" tires mounted to them. I don't particularly like them, but they are the better looking ones I want to get by with until tires become more important than the other things in the truck I'm trying to fix. Thanks a lot for your input.

I find wider tires on narrower rims work very well. They air down really nice for off-road and the wider tire sidewall protects the rim edge from damage in rocks. I used to run 33x9.50 on 6" rims and find the 10.50s work better, more stable when aired down, less likely to fold over on side hills.
Only downside is that inflation pressure and tire wear can be a little tricky. On mine, I run anywhere from 25 to 50 psi in the tires. At 25 I get a fairly flat contact patch and the edges wear faster. At 40-50 psi, the sides of the tread lift off the road a bit so the center tread wears faster. So I alternate pressures to keep the tread wear somewhat even.
One rule of thumb is tire width no more than 4" more than rim width. Although I ran some 33x15.50 tires on 10" rims for many years with no problems and I currently am 4.5" difference with 10.50" on 6" rims. 12.50" tires on 8" rims are very popular, so that is a 4.5" width difference.

2001 4Runner Limited w/3" Toytech lift - Want 285's
BRAND NEW to your site. Glad to be a new member!
Have looked for a thread or reply to what I'm posting so I apologize if I'm duplicating efforts.
I have a 2001 4Runner Limited. Just starting to build for off-road and daily road worthy. I have Installed new struts, all new Bilstien shocks, 3" Toytech lift front, new 3" Toytech coils rear, and a 1" Diff drop kit front.
Can I fit Mickey Thompson ATZ P3's -285/75/16 tires on this setup without trimming front fender flares? I'm using factory rims.
Will the tire rub the IFS?
Thanks!
J
