<DIV>Hi All,</DIV>
<DIV> </DIV>
<DIV>As my sig says I have a 98 Suburban 4x4. I currently have 265/75/16 Coppers on it. I'm going to need new tires this summer. Anybody have an idea how large of a tire I can go to with out rubbing or replacing the rim. Also does anybody know of a site to figure out all the tire codes and what they mean?</DIV>

I would guess that 285's should fit in the wheel wells okay, but I can't be 100% certain of that. They will definitely fit on your rims though.

Tirerack (www.tirerack.com) has lots of good tire info.

Here is a Toyo tire guide to sidewall information





http://www.toyo.com/tires/index_frame.html

For some reason, the link to the Toyo site brings you to the page before the sidewall info page. When you get to the linked site, click "Tire Basics" and then on the next page click "view light truck tire".

k1, 285/75R16 will fit fine, or if you really want you could put 305/70R16 on. The 305's will wear in the center quicker though. I would stay with 285's as they are around 32.5" tall and the 265's you have are around 31" tall.

Thanks for the help. It's starting to make sense now. I question is what does Load Range E mean.

Load range E is the equivalent of the old "10 ply rating" in a light truck "LT" tire. A load range E tire in any given size will have greater load carrying capability than one with load range C or D light truck tire, and definitely more than a "P" passenger vehicle tire.


At this point, I would go to the www.tirerack.com (http://www.tirerack.com) site and look at the tires available there in the size you are interested in. You will see tires of many models, but within models, you will see some tires available with different load ratings. And if you click on tire specs, you will see the load ratings in pounds, revolutions per mile, and lots of other information.


It is my experience that there is trade off between speed rating of a tire and load rating. In other words, the tires rated for higher speeds will have a lower load rating, and those with higher load ratings will be rated for lower speeds. Kind of makes sense, as most people don't tow at over 100 mphhttp://www.dieselplace.com/forum/smileys/Big Smile.gif
