im looking about buying these for my truck also
what is the size difference between a 275/60/20 and the 305/50/20, what does this convert to?
i have nitto mud grapplers now, how much better are the coopers milage wise?

 

I think the size is alittle bigger and would need a leveling kit to make these fit and not rub. I have heard the coopers can go 35,000 miles np but that is what im hearing. Good luck.

 

Well I've had the Cooper Zeon LTZ's in the stock size on my truck for 20 thousand miles now and I have a lot of tread left. But I do rotate my tires every 5000-6000 miles to get the most out of them. As for traction they are definately better than the hp's that came on the truck. But bf goodriches I'm sure would give you better traction especially in the snow where it's better to have a all terrain tire with smaller tread which gives you more contact with the road. But the price difference is'nt worth it. I've driven them in two Michigan winters with no problems. I'd definately buy them again, and I expect to get about 40 thousand miles out of them.

 

thanks for the insight, that is very helpful and apprieciated.
i was looking at 305/50/20 but that to my calculations is just a 32, im running 35's now...but the 275/60/20 converted out to like a 34 but not as wide, so idk what i should do...

 

The 275/60/20 Cooper measures out to 33". I measured them when I first got them, the 305/50/20 is a little wider tire but is a inch shorter. A wider tire is better in the mud but worse when driving in the snow. Glad I could help.

 

Ive had them for two weeks now in the 20'' size and we just got hit with 2ft of snow. I have been all over town with these tires through thick snow, hard packed snow and ice and have yet to have an issue. I say for the money, they cant be beat imo. MUCH MUCH better than those sorry excuse for a goodyear hp

 

Where you buy them at?

 

I have been looking into this tire as well, but almost want to jump the bullet to get a little larger than the stock size. I am also looking at the Nitto 275/65R20 terra grap. which comes out to a 34.09" tire. Still trying to get feedback to see if it rubs or not on my leveled '07 2wd. Does anyone have this tire?

 

doesn't rub

 

What about the Nitto 295/60R20 terra grap., which comes out to a 34.45" by 12.36" width. Do those rub??
