Maximum tire size 16X7.5

Hi guys,

I just bought a Pro comp 3" lift kit and i will have to put new tires next summer. I have Fj cruiser TRD wheels that are 16X7.5. Can i go as big as 285/75/16 or it would be too width to clear front suspension components.

 

285 75 16 will work fine i ran the stock 16x7s with 285's no problems for a year. I just switched to aftermarket.

Keep in mind if you do run the 285's u will need wheel spacers or the tires will rub on the ucas

 

False. Ive been running 285/75/16 KM2's on TT's for a couple years now, no spacers. Never rubbed the UCA's.

 

yes but did it was stock wheels ? or you had aftermarket wheels with more backspacing ?

 

Same wheels, different color. No spacers. Have about 14-15mm between the inside of the tire and the UCA. It's never been an issue, zero rubbing.

 

Are the factory tacoma wheels the same as the trd fj wheels, dimensionally? For some reason I though the backspacing was different between the two. I could certainly be wrong, though.

 

TRD Off-Road Wheels:
16x7
+32 mm offset
5.25" backspacing



TRD Sport rims
17 x 7.5"
+30mm offset
5.5 backspacing


FJ TT
16" X 7.5"
+15mm offset.
4.5"BS

 

Thank you Boone for the precision. Nice rig BTW !

 

Anytime. Hope it did some good. Thanks man.

 

Im new to this wheel and tire setup. Im putting a 3inch lift on my 2006 Tacoma and the wheels I want are 18x9. They come in 2 different offsets.
-12 with 4.5" backspacing or +12 with 5.5" backspacing. I need some help?

 

What size tires are you,running? Regardless I'd get the -12 4.5 bc this will allow big tires and give you a nice stance

 

I'm thinking of running 285/75/18. I don't want them to stick out to far. Do you have any idea how far they would stick out from the stock flares if they are?

 

More outward (numerically negative) offset means the tire steers over a wider arc -> more fender/cab mount trimming required to fit large tires.

 

You will. Need the 4.5in backspacing then I have -6 offset you can look at my,pics or Google for -12

 

Yes correct if bigger tires aren't a issue then the higher offer is fine but as he wants 285's the 4.5 bc -12 wheels are what he needs unless he wants to run a spacer or find different t wheels with a higher offset and keep the 4.5in bc

 

^I had a good 1/2" of clearance between my 265 tire and stock +32mm offset wheels. 0mm offset is enough to clear 285s. No need to go to -12mm.

 

Ya i never said it was he asked what wheels he needed to run 285 75 18s out of the two choices the the -12 with 4.5in bs will work not the +12 with 5.5in bs. Or he can run a spacer with the +12 or just,find different wheels in general with 4.5in bs and higher offset.

 

The wheels are Ultras and the style im looking at are 18x9 only come 2 ways +12 with 5.5BC or -12 with 4.5BC. If I go down to the 17x8.5 they offer them +1 with 4.79"BC. I quess what in trying to to is buy this wheel but I don't want it to stick way out. 1/2" past the factory flares or flush would be perfect. I really appreciate your help guys trying to figure this rim spacing.

 

-12 will stick out pretty good but it would look good. You might want to go the +12 route or down to thw 17x8.5 and play with spacers or not get as big of tires then you could run the +12 or the 17x8.5 wheels with no uca issues

 

You may have to go down to a 275 series tires tire and run the +12 5.5in bs...research it or have someone else confirm if it will work and not rub in ucas
