well, i have a 1998 toyota tacoma xtra cab 4x4 with a 2.5 inch lift, and it has finally come to get new tires. but i'm a college student who is strapped for cash so would it be a bad idea to put 33x10.5 15's on my stock 15x7 rims or should i stick with the 31x10.5 15's that i have?

 

as far as the rim is concerned 7" wide should handle the 10.5" tire with either the 31" or 33" height.

Don't know how much of a difference 33" over 31" will make if you don't regear since you are a later model with a V6. Surely someone will post up with experience.

 

it will not harm anything putting 33x10.50 on a 7" rim. also, you have a 3.4 therefore, its not as much as a problem to regear. you'll find lower result of MPGs, but only slightly.

 

well the truck has 4:10's so even though that's not the optimal gearing, it's a start. the only drawback. my tacoma has the 2.7 4 cylinder. even though it's a step above my 22re, it's not exactly a power house despite all my power adders

 

It may be best to stick with 31's till out of school and land a good job. I haven't found a cheap way to regear, but my rig had 33's with 4.10 on it when I bought it. I was driveable just nothing to brag about. Tough call.

 

33-10.5's will be fine on the stock rims. Weather you want 33's with out a re-gear is up to you, some would say 33's and 4.10's with no problem, others would say hell no! I say it's up to you.

 

I am running 35x12.5's on a 15x7.5 4runner rim with no problems. I was also running them before regear with 4.56's

You should be good

 

Yep, good fit:

33x9.50 and 10.50s on 15x6 stock wheels:

 

well, the concensus is that 33's might not br a good idea with 4:10's and a 2.7 4 cylinder, what about 32x11.5 15's?

 

I'd choose height over width, but if you dont do much wheeling it may be a wash to you. 33's and a 4cyl are bad, definitely managable though, you will want to regear in the future.

 

i might just get the 32's a little bigger but easier to manage without regearing

 

Meh... Toyota are slow regardless... ROFL.. I didn't notice much going from 4.56's to 5.29's with 33's or 35's.

I'd roll 33x12.5's

 

I am in the same situation as you are. What happens with a 10.5 wide tire on a 7 rim causes a bowing of the tires and loss of tread pretty quickly. So if you want wider tires and get your money out of them look for a wider rim, also make sure you can get the rim on without them rubbin the calipers in the front. I had to put a 1" spacer on mine.

 

Uh its called running the right tire pressure. I had absolutely no issues with 10.5's on stock 7" wide wheels. Tread wore evenly. And now, I run 12.5's on 8" wide wheels. No issues.

 

X2 there. I run 10.50's on stock 7" wheels and have no issues. When I need a little more traction I just let some air out of them. You'd be surprised how much traction you get out of a 10.50 at 12lbs of air.

 

You'll be absolutely fine with 10.5's on a 7" wheel, no worries.

 

related, since the question popped into my mind anyone ever run 33 X 13.5 tires on an 8" rim?

 

along time ago i had mickey thompson 33x14.50 on 15x8 stock jeep cj7rims but they were really soft compound ,they had like 25 or 30 pds of air . they wore out fast.but didn't seem 2 have any other issues .they were like a sand tire ,u could hear me coming from a block away!

 

I haven't but I do know that a lot of folks run 12.50's on the stock SR5 wheels which are 7's so a 13.50 on an 8 shouldn't be any different.

 

i ran 10.5s on a my runners stock wheels no problem wore evenly, but now i run 10inch wide wheels and i love how it spreads out my tread on the trail.
In fact i have 2 15 inch aluminium 10inch wide wheels i will sell you for 25 a piece plus shipping if you want to do it right and go with wider wheels
