A flat Good Year Wrangler SR-A set the tire shopping in motion, and a 10% off sale on Nittos convinced me to try the 35x11.50r20 Ridge Grapplers. 

 

My goal was to get as much tire as possible without having to adjust the suspension so as to retain the stock ride, keep costs down, and achieve the aesthetic I like for modern 4x4 trucks. I was prepared to crank the front keys a few turns for up to 1" of leveling, but my preference was to avoid this if possible.

 

Ridge grapplers have two sidewall designs on the tire; one side reminded me of Transformers, so I went with the more subdued sidewall. This doesn't impact fitment.

 

After about 20 miles of driving and some parking lot testing turning the steering back and forth, the tires fit fine with only a few close spots throughout the range of motion. I've seen people report frame rub at full lock with these sizes; it hasn't happened to my truck yet, but I wouldn't be surprised if it rubs mildly while turning sharply over rough terrain. 

 

Rear clearance is fine. 

 

A few tips:

  • Check the actual dimensions of the tire you're choosing. The Nittos are 35s, but the actual diameter is about 34.7". Each manufacturer is a little different, and most list the true dimensions on their websites. The same applies to metric sizes - a BFG may be narrower than a Toyo.
  • Looking at my truck, 35x12.50r20 would have fit too, but would probably rub on the wheel wells while going over bumps during a turn. The 11.50s provide just enough extra room that my truck has yet to rub, though my mileage count is low (20 miles since install) so I'll update this thread as I add miles.
  • Expect to lose fuel economy. No data yet, but I anticipate a 1-2 MPG drop. 
  • Aftermarket wheels change everything. The popular offset or "poking" look makes it harder to stuff big tires without a lift. If you're changing wheels and tires, disregard this thread.

 

What's next?

 

Fresh oil, a detail, and maybe a front window tint. I'd like a Corsa, but they're $$$. 

 

Please excuse the dirty truck:

Nice truck, like the green, looks great.

Nice tires, running them myself,  285 75 18, I really like how quite they are, as quite as the Michelins that they replaced.

Those are Ridge Grapplers not Trail Grapplers, big difference in road noise over the Trail Grapplers.

Nice. Made appt. for new shoes today - going with Cooper AT3 XLT (LT275-70R18). I "guess" $1000 isn't horrible installed :)
