Larger Tires on Stock Suspension

What are the largest tires you can fit on the R51 on stock suspension without rubbing/causing issues?

I don't see a need in my case for any sort of lift but I do drive in some sandy conditions and would like to get some AT tires when I am due next.

2012 Silver Edition

Thanks!

I have an ‘05 LE with 17†wheels. I replaced the front struts with factory stuff, and put the AirRide bags in the back.
I just put 255/75 R17 Goodyear Wrangler Duratraks on there, and they clear. They come close to rubbing the front mud flap while turning, but no contact. I love the tires so far, especially with the winter we’re having.
Discount Tire was great to work with ordering the right size, and verifying fitment when the tires arrived. I ordered 5 of them to have a matching spare, and it fits fine, as well. I don’t have any pictures on the forum, but I could email you some if you want.

Also consider upgrading your brakes before adding the additional rotating mass of larger tires.

2011 SV here. I have stock 17s and run 265/70/17. Raises the height about an inch which was good for me as I didn't want to do an actual lift. Info is in my signature. Also, if you've never driven with larger tires before, your gas mileage will drop depending on the size and the load rating of it. I went with C rated tires and lost about 1 mpg going to the larger size. I suppose if you went with P rated tires the difference would not be too crazy. My stock tire size is 265/65/17.

This might help too -- viewtopic.php?t=5557

Thanks for the info, this is what I have been leaning toward with the size and BFG AT's. The extra inch of height is more than enough anyways!

My Pathfinder has 17" fuel wheels wrapped with 255/65's. No rubbing issues whatsoever. This tire size is almost the same with 265/70's but with less sidewall.

PF Flyer: Did you end up getting those AT's? If so, how did they work out?

CRC11007: Just new stock components in the front (no lifts/levelers), correct? Do the AirRide bags provide any lift?

Would going from stock tires (265/65R17) to something larger (275/70R17) require new brakes?

Sorry for the delayed response...
After replacing the front struts, I did not notice much of a difference in height. I suppose the factory springs may have settled over time, so now it’s back to where it was originally. The AirRide bags don’t noticeably lift the rear in my opinion, but it makes for a much more controlled and compliant ride, especially for towing. I went with P-rated (passenger) tires, instead of the LT-rated (light truck) tires. The P-rated ones are not as stiff, and since I don’t tow that much, not necessary for me. The LT tires are heavier, as well. The upgraded brakes for me were an absolute necessity, as I felt the factory brakes were always under-powered, let alone with larger tires. It’s an easy upgrade, and one that I would do before any other.
I know SMJ999 just did a write-up on the V8 brake upgrade recently. I did the same V8 conversion last year, but a little more budget-friendly. I think I spent about $550 for the whole job. As long as you have the 17-inch wheels, you’re good to go.
