Widest rim with 6 inch lift

AZbum · 07-20-2011, 11:26 PM

Im about to slap a 6" Rough Country lift on my titan. I bought some 35" super swampers (35x12.50) on a 15x10 rim. My question is. Will I be able to roll around with these rims or am i gonna be constantly rubbing. If you have pics that would really help to get the look down.

how about 15x12s?

15's will not clear the brakes on your truck.

Pretty much need a 17" on an older Titan, and an 18 on the '08+ as the minimum. There have been a few people that have fit 16's with grinding on the '04-'07. Look for an 8.5" rim width as maximum for less rubbing potential, in a 4.75" to 5" backspacing, at least with their old UCA's.

Yeah, the other posters are right... You will never fit 15 inch rims over the brakes on our trucks. You might as well start looking for a jeep guy to sell those wheels and tires to.

Also as Norcal pointed out, backspacing and TIRE width are the key points... I'm running 35x13 on OEM Rims with 1.25" wheel adapters and had to Sawzall the snot out of my fender pinchwelds where if I wasn't too lazy to remove the adpters they would've fit just fine. 8"-9" rims fit great, a few people have fit 10" rims but finding the correct backspacing on 10" rims can take alot of work.

dam that sucks bad lol ok well i guess back to the drawing board... ill have to get rid of these tires and rims

With a 6" lift would i be able to do a 37" tire on my stock 17" wheels with a 1.5" spacer on the two front rims?

Fox Delta ran 37x13.5 Toyo M/T's on the 17" off road rims, with a ProComp lift plus coilovers, but wheel spacers would cause too much rubbing at the pinch weld. I think the RC kit is higher than the PC stage 1, (no coilovers, just a big strut spacer), so maybe with a skinny 37" on the stock 17's w/o the wheel spacers. You would have a better chance with one like the BFG A/T KO 37x12.5R17D which is 36.3" diameter, and about 12.8" wide on a 10", so would pull in to about 11.8 to 12" on a 7.5" with rim. Probably need the pinch weld mod and it might rub the RC UCA's.

thanks man ill start looking around and see what 37's i can run with the RC lift

Dropped off the titan today for the 6" RC lift install... got a hold of some 37" CL Junkers and told the shop to throw them on in the mean time until im able to get some new rims and 35's... I told the shop to mount the 37x12.50 on my stock 17x7.5 wheels... They said they would try... Will this work??? I mean will a 37x12.50 actually grab on to a 17x7.5 wheel???? Truck will be ready on Wed I'll have pics up

As mentioned above, it's been done. I probably wouldn't do it, but a lot of people run 325s, which tend to be wider than the 12.5" tires on the stock 18x8" rims. Never heard of anyone losing a bead, and the guy with the 37x13.5R17 Toyo M/T's on the off road rims aired his down to 12 psi or so when we were on a snow run. We weren't ripping or anything, just were getting too much tire spin on the hard pack and ice on the forest road.

You will likely need to trim at the pinch weld if you aren't running coilovers. Hopefully they are on the small side for 37's, like the BFG KO's I mentioned ... I guess if they are junkers, most of the tread will be gone which will make their diameter smaller, closer to 36" even if they were true 37's.

Thanks for your response man, I actually looked for the BFG KO's and those are the ones I got thanks to your recommendation 37x12.50. Now we will just have to wait and see if it can be done and mounted on the 17x7.5 wheels... The shop doing the work is BDM Customs out of Tempe, AZ and they will be trimming anything that gets in the way of the actual tire so when I get it back it should be pretty trimmed up...

My 2 Wheel Drive Titan on a Rough Country 6 Inch Lift with 37x12.50 BFG Tires on 17x7.5 Stock wheels. All fit in with no cutting or trimming of the plastics. Didn't rub once driving around and making turns.

Looks great. Glad they fit.
