Looking to put tires on my 2007 Chevy Silverado Classic 4x4. Generally, the truck is a passenger car and 90+ % of my driving is done on paved roads (albeit some not in the best condition). And I do take the truck on some log and dirt roads from time to time. Lastly, I do plow with the truck (my 400' drive and a neighbors) but I take the plow off when not in use. The guy at the tire store has continually suggested I switch from LT to P-metric tires. But I've been inclined to run LT anyhow.

What's your opinion/experience? Anyone see any really good reason to switch from LT to P-metric given my driving conditions and use?

(Current tires are General Grabber AT2 LT265/70-17 which I've had very good luck with and this set has nearly 50K on them with another couple thousand miles left in them IMO...sort of inclined to run another set of these)

Thanks.
Rob
