largest tires for 99 Yukon?!

[stickxxxi]

Just got my new baby this evening....tires look like bike tires....I have the 245s.

Will the 265s make much of a difference? Anything bigger that will fit?

Congratulations! My neighbor has a '98 and he's running 265s on stock rims. To my eyes they look good. You may be able to go w/ 285's - I'd check with a pro...or simply go to www.tires.com to see what they show. Good luck...

Take care,
Jerry

username Yukon99 left me a reply stating that they had 285/75/16 on their 99. I have a 2002 with 305/70/16. There is a very slight rub on the wheel well only. Nothing for me to worry about.

Thanks for the replies. I went with the 285/75/16. I love them!

hey guys,

I have a 99 Denali with 20" rims. not sure of the tire size, I do not know much about cars but am really starting to get in to hooking my truck up, so far i added the 20's, a billiet grill, the billet grill GMC emblem, flowmaster with duel exhaust.

Now as far as tire size what # lets you know the width of the tire, and what do you think i shoud go with.

Thanks.

Using the example above - 285/75/16 - here you go:

285 = tread width, expressed in millimeters.
75 = aspect ratio. This can be confusing. It's the ratio, expressed as a percentage, of the sidewall height to the tread width. In this example, the sidewall height is 75% of 285, or 213.75mm.
16 = wheel diameter.

I'll take a wild guess that your size is something like 285/50/20. The size will be displayed on the sidewall. The reason I say that aspect ratio can be confusing is that a lot of people mistake it for width. For example, a common mistake is that a 50 series tire is wider than a 60 series tire. Not necessarily true, and you have to use the tread width to say for sure.

Lots of other boring stuff on tires - I won't put you to sleep any longer. I recommend checking out the tutorial at http://www.tires.com if you're interested.

Thanks,

I will check it out, one more thing the height between the tire (the ground to the rim) does this make for a better ride? lot of Pot holes here in NY.

To protect against pot holes you want as much sidewall as possible, so you're absolutely correct - the more tire between the ground and the rim, the better. I'd recommend sticking with a 70-series or higher, but that's just a personal take. Depending on the width of the tire, a 60 series might offer plenty of sidewall...

Take care,
