Switching tires... Problem?

Okay so right now I have the equivalent to 33/10.50/16 but I'm looking at getting new wheels and tires. I can easily find 33x12.50x15 wheels and tires. Is it a problem going from 16 inch rim to 15? What will it all affect if anything? I've been told something about the brakes won't work correctly or something idk. But some help would be nice before I decide to go and shell out money.



Thanks in advance, sorry if this is in the wrong section.

Shouldn't affect anything unless the smaller wheel gets in the way of your running gear/steering etc. A quick visual check should suffice. For instance, I tried putting some 16 inch alloy Tacoma wheels on my 84' and the wheel was too wide to run without a wheel spacer as the wheel came in contact with my steering arm.

15" is the stock size, so you shouldn't have an issue.

I recently purchased a 94 toyota pickup ex cab 3.0 with 7.5" of lift and 17" Fuel wheels and has 35x12.5 MT and my brakes have been terrible since I purchased it. Bought new brakes anticipating that the pads were worn. Nope. Bled the brake lines in the front...still same problem..dont know if it is because of the wheels but I am having issues with them.

Bently----Doubt the tires have anything to do with the braking issue although with that lift and tire combo will affect braking somewhat. Also, did you just bleed the front brakes? Bleed all corners starting at the farthest wheel. Usually r.rear, l.rear, r.front, l.front in that order. Try the search option. I found this literally 2 mins after I read your above post. https://www.yotatech.com/forums/f116...eeding-249603/

Likely poor braking due to not adjusting the rear brake proportioning valve properly:

- http://www.4crawler.com/4x4/ForSale/...l#LSPV_Bracket

Not compensating for the lift can essentially eliminate the rear brakes from the equation.

like everyone else already stated, stock is a 15"x7" wheel with around 4.75" BS. since the 33x12.5s are so wide, you will need a wider wheel (8") and less BS to push inner sidewall away from your control arms. I believe a 15x8" with 3.5-3.75"bs wheel is what you want to be able to fit those tires....but remember your bigger tires will most likely rub in other places like the firewall and/or bumper, mine did. BFH and cutoff wheel were my friend
