[standardmoose]

hello all just a quick question, i looking at going from 255/70r18 to a 265/70r18, im on my stock 18" xlt alloys, has anyone done this on a 3rd gen model and if so any problems?

cheers guys

Logic to me says that you should be fine. Essentially you are adding 10mm width and about a .5 inch in height. Put your wheels to full lock and see how close to the frame they come. If you have more than 10 mm of clearance, which I am sure you will, then you are fine there. Then find a way to articulate the wheels (basically have to make it "bottom out") and measure there, if more than a .5 inch, then you are fine. Hope that helps.

Tire Question

Zombie - how do those tires ride? I've use the TA/KOs in several sizes in the past but never in this particular size. I'm looking at going to the 275/65/18s but am a little leary of an 80 PSI tire that weighs 9-10 lbs more similar sizes like the stock 265/70/17s I am replacing.

How about road noise?

275/65/18s retain the stock diameter and won't throw off your speedo....

i like them. they are smoother than the Nitto NT420S tires that were on here with my 22's. They do fairly well in mild amounts of sandy mud. I would recommend them.

The 70 is a percentage of the width. So the wider he goes the taller the sidewall.

wow you got that all wrong. the width is your 275 or 285. 70 or 75 is your aspect ratio, or percentage of the width of the tire that represents your sidewall height. so if you have a 12" wide tire, and your aspect ratio is 75 you have roughly 9 inches of sidewall (4.5" above your rim 4.5" below the rim). make sense?

Went with the BFG ATs

275/65/18s with KMC XD Monsters, 33mm offset. No change in ride height, tire diameter, or speedo calibration. Big change in looks. No longer see myself coming and going everywhere.

Pondering next mod....
