Buying new tires need some assistance

Ok here is my plan. I plan on buying Pro Comp 7005 17x9 wheel it has BS of 4.75 and an offset of -6mm. I tires I want are Nitto Ridge Grapplers. Now this is where I’m getting confused. I was bouncing between 285/70r17 and 295/70r17. I finally decided on getting the 285’s. My plan was to buy them off of quadratec. After I pick my wheels and and go to pick the tires the only tire in that size is a reg 285/70r17 I believe it is load C. That the total thread is measured at 13.5 and total weight is about 50lbs but I also seen on Nitto website they have a LT285/70r17 tire which is E rated but has a deeper tread at 16.4 and weight of 57lbs but I am unable to select this tire for a 17x9 wheel the largest wheel suggests a 8.5. Question is why is this and which tire is better? Obviously the LT is more expensive because I’m guessing it is a higher ply. Would it be dumb to buy the cheaper ref 285? Or should I go with the LT295/70r17? I’m a little thrown off with all this.

I can't vouch for the wheels as we selected a different set and I believe I posted this in another one of your threads. Anyway, the wheels are 17'' x 8.5" and the tires are 285/75/17 (E) 34'' x 11.5 and yes cost us 298.00 per tire. Total cost for wheels, tires and even my own Standard Brand valve stems: a little over $2,800. Just make sure your tire specs are what you've entered here cause a 12.5 tire would or should be your max. Forcing your tires and wheels out that far will cause some serous issues with barrings etc.

Yeah I would like to stay a littler narrower than 12.5. So for the load rating it shouldn’t be much different for the to different 285’s? Do you think those wheels will make them stick out to far past the fenders? They are stock fenders

Again, I've used a site called wheelsize.com and added in some of my wheel and tire specs in order to determine what wheels and tires would best suit out jeep, Once I was able to find that the wheels did not stick out as far, I turned my attention to tacomaworld and their tire calculator. I think the -6 is a little past the safe mark or zone on the jeep. even our 10mm was out but because the tire actually curved back in towards the jeep's fender flare we're getting the desired look without going skateboard.

Lets put it this way, before the new wheels and tires, our jeep handled like one of those old fashion steel roller skates. A little top heavy because the stock wheels didn't offer a suitable stance. yet in your case, the wheels are going past that sweet spot almost to the point where one is looking as a skateboard stance.

Just check the wheelsize site and compare your current stance and the new stance you're attempting to achieve. But I really thin 10mm would be your max or safe zone on any wheel offset.

I'm not able to offer much help, but don't forget to consider the patagonia brand. They make amazing tires for a fraction of the price of other brands, and they have been performing awesome based on everyone's reviews. https://www.amazon.com/Milestar-PATA...language=en_US

Best of luck and cheers!

I would not use an E rated tire on a jeep. Its not a 1 ton truck towing 10k. Cs are the best "ride". Ds would be next up.

I ran Cs when on 35s since you can find them. when i went to 37s in the tire i use they only made them in a D min.

@222Doc Your off road driving is way different than ours and by no means would we use or abuse Load E tires the way you drive off road. We're perfectly happy with out E tires at 38PSI. But if we had to do it again or was forced to do it again, I prob would have went Duratrac D's We've seen nothing but even wear on these nitto's they have a slight hum to them but nothing like swampers etc. So to answer one of the other opers about silent or quite tires.. these Nitto's are very quite.

If the Oper wants E's then he must have a good reason like we do.

E rated tires have very little sidewall flex, therefore ride stiffer. An E rated tire is a light truck tire, designed for higher loads. A Wrangler is no where near the weight. I wouldn't run an E rated tire unless it's the only selection in the tire style or size.

Load range affects a Jeep more than on or off road.

I just wasn’t aware of the differences between them is all. I have no need for the E. They also have a LT 285/70r17 which is a Load C. Would this be a better choice over the regular 285/70r17 ?? Thanks a lot for all the advice

I wasn't suggesting that you purchase E tire, but our purchase what we wanted. I'm under the impression that either load C or D would best suit you driving style. So yes an E tire is very stiff and we've taken that into account. In fact most here would suggest and did suggest that the load E tire should have a lower tire PSi. But after driving one week with a lower PSI we found the ride was better at a higher PSI or 38psi. I feel you'll be taking a few more trails than we will so the C load would best be suited for you. I was just concerned with the width of your tire and not the load rating.

Getting back to the question of size since most reasonable people will agree that a C or D is better for Wrangler than an E on the street, 285/70-17 is a common size and is only slightly larger in diameter than a stock JK Rubicon tire, with most of the size difference being in width. As an additional point of reference, a JL Rubicon comes with 285/70-17 stock.

Regarding the 285 being too wide for a JK, many of us are running 315/70-17 tires. It’s what I run on 17x9 wheels with 4.5” backspacing. I have stock fenders.

The second generation JK’s are more forgiving regarding gearing than the first generation.

I went deeper than normal with gearing due to occasional towing an enclosed trailer. As a result my Jeep’s acceleration is pretty good without the trailer. My lockers and gears are all made by Yukon, so if there is a problem, I don’t have to deal with different manufacturers blaming each other.

Not to increase your confusion, but consider Kendra 35x10.5R17 tires. They are actually 11Ē wide but they fit inside the flares and are a light 35. Mine measure 34 actual after mounting them on the Jeep. These are D rated too.
