I am overdue for a new set of tires - my current 265/75/16 Nitto Terra Grapplers have nearly 64,000 miles on them. I've been very pleased with this size but keep wondering if a 33" version would fit. Yes, I've spent too much time already reading through old threads on this subject, so please bear with me.

In the nearly 15 years I've owned the truck, I've gone through two sets of 265/70/16 Dunlop GrandTrek tires, one set of 265/70/16 Michelin LTX M/S tires, two sets of Bridgestone 275/70/16 Dueler A/T REVO tires, and two sets of 265/75/16 Nitto Terra Grappler tires in Load Range D. This in nearly 348,000 miles...

My truck does daily local driving with long road trips several times a year. We also drive it on the beach 5 or 6 times a year. Otherwise, I do not off-road or trail drive the truck.

When the truck was two years old, I installed a factory-new set (4) of tall '99 4Runner coils, Bilstein HD shocks, and 1" rear spacers. Since then I've replaced the Bilsteins once with an identical set. So the truck has spent the last 13 years with this suspension height and I've never had an issue with any of the three tires sizes touching fender liners, the frame, etc.

This morning I went to the Nitto Tire site to refresh my memory on sizes & specs. Nitto offers the Terra Grappler in two version of the 285/75/16 size - a D and an E load range. The D version is both smaller in overall diameter and narrower than the E version. Compared to my current 265/75/16 D Terra Grapplers, the 285/75/16 D tires would be:

1.14" taller (total), or .57" greater in radius (32.68" vs. 31.54")
and
.59" wider (total) or .295" wider inside & out (11.34" vs. 10.75")

I'm on stock wheels with the narrow factory fender trim. When I look at the room between my current tires and the UCA (on the ground or drooped), I see no reason why a slightly wider tire wouldn't work. Ditto for available clearance as the wheel is turned lock to lock. I would really appreciate some fresh thoughts on this - keeping in mind all of the tire sizes I've run over the years, my suspension, and the intended use of the truck. MPG and acceleration changes are not important in this case.

There are no fresh thoughts on this... only the same regurgitated thoughts told by different people. The facts are there. Make a decision already :-)

 

yes, the larger size will fit - but if you go up a size are you also going to regear your differentials to compensate or just leave your stock gearing?

 

I'm working on it!


My intent was to leave the 4:10 gearing alone and enjoy the scenery a bit more as the truck works its way to cruising speed.

I dunno then, I'm inclined to say stick with your current size. 0.5" more radius/height isn't going to be that much in terms of offroad gains, but it's going to likely cost you more once you factor in the extra weight, strain from gears, speedo/odo being off, etc etc. Might be smarter to just go with the same size tire and perhaps install some rock sliders so you can slide over the object you needed the extra clearance for.

 

there may be slight rubbing

 

Still haven't made a decision yet...

You don't want to stick with what works. I am currently on Revo 2s, nothing like the original ones and hope to be back in some Terra Grapplers soon, stock size of course.

I'd say there will be some slight rubbing at full lock on uneven terrain. Otherwise you should be OK.

Nice looking rig. You have to garage that thing sometime in the year.

 

From what I gather there is no Hard core Off Road driving !!

There is no real world advantage other then looks.

Perhaps another Tire manufacture is now making them

Unless you have Installed some Video Cameras you can`t see your tires when driving

Are you correct that The load range D tire is larger in size then your current Tire .

Did you mean the load range E is slightly bigger ??

What is the load rate difference between the D and E ??

Going to the E rated tire could let you know your in a truck do you need or want the The extra weight carrying capacity ??

In my Truck there is quite a difference in ride between the same tire with a different weight capacity

Find some one that has the tires mounted on Toyota rims go try one on for clearance know for sure .

I would bet gotta be someone within 2 hours of where you live.
