35x12.5x18 -VS- 325/65/18

]<ing said:

Ordering a CST 4" lift, and I need to nail down the rubber I'm going to go with. Going to mount them on my stock 18s. Nitto Terra Grapplers.

Main question is, is the 35 taller than the 325/65? I realize that the 325/65 is wider, but in many of the pics that I've seen, the 35's look bigger overall.

Finally, any advantages / disadvantages to either?

The advantage of the 325/65R18 in the Terra, is it exists. You would need to go to another tire for a 35x12.5R18LT.

The disadvantage of the 325/65 with stock rims is that they will likely rub on the CST spindle. If you get new rims look for some with a 5" or even a 4.75" backspacing to get some more inner clearance than the stock's 5.5" backspacing.

Or try a Toyo in a LT285/75R18 or a Kumho KL71 M/T in a 35x12.5R18 which is really skiny, like around 11".

I just this past weekend went from a 325/65 Procomp Extreme A/T to 35x12.5 Extreme A/T. The 325 is 13.5" wide and not (but close to) 35" tall. IMHO The stock 18" rim is too narrow for the 13.5" wide tire. I had crowning on mine (center portion of tread wearing faster than outer) The 35x12.5's do look smaller but I can tell you for a fact my truck sits taller with them than the 325's. With the 325's I was almost an inch lower than a buddys Chevy with a 6" Rancho lift and 33's. Now (I parked next to him yesterday) I am an inch or so taller. And my 325's rubbed on the frame rails at full lock big time. 35's dont. I also think the 35's weigh a little less than the 325's, my Braking feels much better than before. Hope this helps...if my sig pic truck is clean those are 35x12.5 toyo M/T's (can't see it at work) If covered in Oklahoma mud, those are 325 65 PC A/Ts.

Damn - I was sure that the Terra came in a 35. Must have confused it with the Trail. Thanks for pointing that out.

Gregg at PRG says that the 325/65 Terras on stock wheels wont rub with a 4" spindle lift. Other posts on the board seem to verify that claim. Am I missing something? Honest question.

Thanks for the heads up.....

Sig pics are the 35's then. That's a beautiful rig man. What kind of lift do you have?

Wondering what PSI you were running around with the 325s? Seems that "crowning" could be caused by over inflation. Just wondering.....

I was really set on getting the Terras, but now I'm going to have to rethink this. I'd prefer 35s I think, but they price difference on the 325s would pay for a full size spare.

Here's my .2 Hope it helps. I have the 06 2wd with 3" body lift, 2.5 level kit (prg) on toyo open country 35x12.5x18's on aftermarket MB wheels. The 35's look tough, sound tough and ride fine. There is minor rubbing when backing up at a serious angle (I have not done any fender trimming). According to Discount Tire the 35's weigh 67lbs.. I am currently talking to a forum member about getting his 325x60x18's Nitto Terrras. According to Discount Tire those weigh 61lbs..

The 325's are 1.4 " smaller and a 1/4" wider.. (Again according to Discount Tire) So you will lose some height I guess.. But in my opnion not much. I was mainly trying to go with something lighter to help out the mpg. I drive 80 miles round trip to work everyday, getting 14mpg. Not bad, but trying to improve it.

Hope this helps

I just switched to the Nittos 325 60 18 on stock 6 spoke. There a smidge shorter than the 275 70 18 I had but the width is awesome no rubbing woith 2.5 level and tread looks great. about .25 outside fenders no big deal. Gas mileage has gone up 1 mpg great ride load D from the E that I had.
Good luck!

Greg would know. In the back of my mind I was recalling a 33" Terra in a LT325/60R18, that have rubbed on a CST 4", (there might be some that don't). The 4" CST spindle slopes inward towards the top, so with a bigger diameter tire like the 34.8" Terra in the LT325/65R18, the tread at the shoulder is farther away than with the 33.

I don't know if you plan any off roading where you are going to air down, but if you were aired down to 12 psi for sand or snow maybe you would have issues with the sidewalls hitting, but maybe not.

To the other posters with leveling kits and body lifts but using the stock spindle ... different animal than the CST spindle lift. You can use even a larger backspacing than stock and not rub the stock spindle. I know that many use 5.71" to 5.75" backspaced aftermarket rims and various large aftermarket tires without having stock spindle rubbing. And some low pro street setups can go somewhere in the 6.3-6.5" backspaced range with stock spindles.

I have 325/60R18 Terras on 8.5" KMC with 5.25 backspacing. There is about 3/16th~1/4" space between the tire a CST 4" spindle. I think you run into problems with tires such as the mud gapplers with the huge side lugs. I would go for it. If need be get some small spacers. Either way if Greg says they'll fit, they will. He does know his stuff. I'm sure he gets asked the same question a 100X every week.

The stock 18x8" rims have 5.5" backspacing so are tucked in 1/4" more than your KMC's. But, often overlooked, is the tire sticks in and out past the edges of the rim more on a narrower rim. Not the additional whole 1/4" more at each edge, than your 8.5's, because the tire also pulls in about 0.2" for a half inch narrower rim, so more like 1/8", so with the more tucked stock rim, about 3/8" more total, and a 325/60R18 will likely rub.

Thanks for all of the feedback. I ended up buying the 325/65 Terras, mainly because I've never heard a bad word about those tires. I'll post pics once the lift and rubber setup is complete.

Sig pic is when I had 35x12.5 toyo M/T's...as far as the lift (3" up front) prg mini lift spacer sits on top of 09 Pro4x coilovers. I ran the 325's at 40psi.

I've had 295 70 17 Terra Grapps and 325 60 18 Terra grapps...good tire..I just wanted more aggresive tread and sidewall. (LOVE the Toyo M/T's..just not the price).
Got my 325 65 PC for $600 for the set used and got the 35x12.5 PC's for a case of beer. :teethmast (rears used more than front..fronts dang near new)
