Thinking hard about getting four of these tires. How are they holding out?

So far I have put on about 2000 miles on the Firestone Firehawks and they are performing extremely well -- good wear, good traction in wet weather, quiet at highway speeds, softer and more comfortable ride compared to the BG Goodrich truck tire I had on earlier.

My buddy and I drove from Seattle, WA to Vancouver B.C. (about 250 miles or so) and he commented positively on the ride.

Additionally, I think Firestone retail outlets have a "sale" going on but if not, they will match Tire Rack prices.

I would highly recommend the 255/70/15 sizing if your suspension is stock height as these are close to the 235/75/15 that came stock with the truck. The benefit is that the 255s will not dramatically affect your speedometer (maybe onl 2 mph-ish faster). Additionally, if I decided to lower the truck, the 255s will tuck under nicely -- both front and rear.

I know it is a hard decision but I solicited input from this Forum as well as others. I have no regrets on the purchase.

I'm running Uniroyal Tiger Paw GTS's, 255/70s and they look good and ride very well with no road noise on mine.. I am going to 275s on it though, as I don't plan any lowering other than dropping the back end to level it out. I just like the look of a fat tire on it!

Thanks 1986swb. I'm going to get them tomorrow I think. The 255s as you say they are 29.1 high.

Albatrossian... the 275s are wide eh? I looked at them but I wanted to fill the hole a bit more. I think the 275s are around 28" high. My '87 came from the factory with 225s and I think they are 28.3 so speedo shouldn't be too bad in either case but I'm getting the 255s.

I like the 255s as I can rotate the tires. Going larger in the rear, you can go as large as 295 but be prepared to purchase front tires sooner than later. Remember, if you go large tires all around (i.e. 275s or larger) they may put more strain on your front end and steering components. Something to consider.
