Its about time for some new tires, and was wondering if I can go any bigger with a stock suspension. Right now the truck has 285/70/17? Can I go any bigger without rubbing?

hmm a 285/70/17 so you have a 4x4 with the off road pkg... - Nitto makes a terra grappler in a 295 that will fit -

Are you looking for wider or taller? Some people are able to run a 34.5", BFG AT KO, in a LT315/70/17 with just a PRG leveling kit ... without trimming. Others have had to do the pinch-weld-mod. So a bit of a gamble. All depends if you have an issue with using a Sawzall, (inside the fender, behind the liner). :)

With the PRG Leveling kit or an adjustable height coilover from PRGproducts.com, (and stock wheels), I would be almost certain you could run a 33.5" Toyo MT, (LT295/70/17) or a 33.8" Toyo AT, (LT285/75/17).

Aftermarket rims is another story ... dependent mostly on backspacing, and rim width.

So the Nitto Tera Grapplers in a 33.2", LT295/70/17 work w/o a level kit? That's cool if they do. They are slightly smaller than their cousin, the Toyo MT.

well - I should say that they did fit on the front of my truck before I got the level kit - Discount Tire mounted the front two for me and let me drive around the parking lot - I had a little less than a finger's width of clearance (on my plastic inner liner) with the steering wheel at full lock on stock OR rims

That's probably enough for owners with a conservative driving style, that use their Titan only on-road, or slow on dirt roads. A level kit definitely gives a bit of leeway.

Good info!

yep I agree and that's why I started with the leveling kit-- its the way to go.
BTW Interco tire makes a 34x10.50/17 (it's the LTB tire) that would fit with a leveling kit on stock OR rims too - it's an agressive tire though

LTBs would be kool for those guys and gals that can afford dedicated tires, but I'm after a general purpose tire, that's good for the commute but isn't phased by hitting a 6x9 river rock at 50 mph. My current, BFG AT KOs have fit the bill, but have gotten slick in their old age. So I'm going to try an E-rated, Toyo AT or MT, (with aftermarket sipping).

im looking at fitting a 305-R18 tires with a leveling kit, will it work or 295-R18?
  • The BFG MT KM2 would probably fit with minimal trimming, if any. LT305/60R18/E is about 32.6"x11.8" on the stock 18" rims.
  • Or a taller size, but in their AT, the BFG AT KO LT305/65R18/E 33.7"x11.8" on the stock rims. Almost an inch taller!
  • You could most likely fit this skinnier 35 too ... the Toyo AT in a LT285/75R18 34.8"x11.3" on the SE or LE rims, with a level kit and maybe the pinch-weld-mod.
  • You might be able to put these Toyo MTs on. They are a bit wide for an 8" rim but because they have a 3-ply sidewall they probably wouldn't flex too much. 33X12.50R18LT 118Q E/10 about 33.0"x12" on an 8" rim.
Note that most of these tires are approved for an 8.5" width rim as their minimum. I had some Toyo MTs in a LT295/70/17 put on to my 17x7.5" Off Road Pkg. rims today, even though their approved minimum rim width is 8", and the tire sales person said there wouldn't be an issue, and I felt no flex on the curves driving home this evening.

I would be cautious of any extra wear on your brakes. The more weight you add will only cause premature wear. It's not like we haven't had enough brake issues:)

The new brakes a fine IMO, and I've put about 40K miles on them, most of has been with 58lbs. BFG AT KOs, (stocks were 43 lbs.), and on very curvy roads with lots of braking. :)

But I agree with you that the heavier tire will take their toll on the brakes. Now that I've jumped up to a 73 pounder, I see Powerslots, and good pads in my future.

Heavier tires will also take their toll on gas mileage, but taller ones counter-act this to some degree since they effectively raise your overall gearing.

Wheel bearings also have more wear, but especially when you go with aftermarket rims that are wider, and/or have less backspacing ... sticking the wheels further out.

I say bigger the better but consider a brake upgrade if you haven't already done so. I see these hip hop guys everyday who put huge rims on their cars but they can't stop em.

Yep, there are hidden costs with most of the upgrades, and it's good that you brought it up, especially being a safety issue. Also, some might not notice it that much until they are towing or heavily loaded, (their truck bed :upsidedow ).

Yep, I mentioned the BFG earlier.
BFG AT KO LT305/65R18/E 33.7"x11.8" on the stock rims.
As far the Nitto it might fit w/o rubbing but the stock rim is an inch and a half less width than the recommended 9.5". It would probably pull in to be 12.23" wide, but would likely flex, and feel a bit unstable, especially because it only has a two-ply sidewall and is a D rated instead of an E-rated tire.
LT325/60R18 D 32.99"x12.83" (9.5)-10.5

The 34, (LT305/65/18) would be a better match for an 8" wide rim, (and a PRG Level kit).

I have the level kit, and the biggest tire the tire place would put on was the 295/70-17 toyo m/t's. I have not had any rubbing, and the brakes are doing great.

Our off road rims, and the XE rims, are only 7.5" wide, and I think that a 295 or 305 is the maximum width I'd want to run on them, and then only in a 3-ply sidewall tire.

Good to hear your brakes are holding out too. I believe you said you've been running those Toyo MT, 73 pounders for 10,000 miles.

I have the 2" leveling kit in the front, 1" blocks in the rear, pinchweld mod and have 35/12.50R18 toyo open countrys on stock wheels that have very slight rubbing at full compression of the front suspension with the wheels turned to one side. No rubbing in the back. It seems to work for me, due to the fact it"s my daily driver and I don't off road this one (too much).
