I knew I needed tires, as the Goodyear Wrangler SR-A 245/65R17's that it came with were just about down to the tread wear indicators.
Then last Sunday, during the Great Battery Expedition, I was rounding a familiar turn in the rain, and the front end washed out and started to slide.
Yes, my Jeep has full-time AWD, but when the tires are turning, and applying power, and worn, they'll skid in the rain.
So, since I'd been researching tires for a few weeks, I decide on what brand and size to buy.
The OEM tires were 9.8" in section width, 65 in aspect ratio, and 29.5" tall. The rolling radius gave them 702 revolutions per mile.
I wanted a wider tire, with close to the same revs/mile, so I started looking at the tire manufacturer's websites to get the specs I needed.
A 275/60R17 would give me a tire about 10.8" wide, with close to the same revs/mile (697, a few less), and I settled on Bridgestone Dueller H/L Alenza tires.
The local tire place didn't have them, but they were in the warehouse, and they had them the next day bynoon.
I went in at 1pm, and was out by 1:45 with 4 new tires, mounted, spun balanced, with free rotation and balancing for the life of the tire.
I also spent an extra $23 per tire for a "certificate" that will replace the tire, for free, if it gets damaged in the shoulder or sidewall where it can't be repaired.
So far they seem to be pretty good tires. The ride is better, and they're a bit quieter than the Goodyears.
And they look great on the Jeep! Just enough extra width to make it look a bit more "serious", and with the 60 aspect ratio they're just as tall, filling up the wheel well nicely.
I do NOT cotton to those running around in SUV's with the 22" rims and the super low profile "rubber band" tires! The first curb they clobber will chew up the rim, and probably wipe out the sidewall.
And I always take it easy the first few hundred miles on new tires, checking the pressure, and retorquing the rims after a 100 miles or so.
