Hello all, my name is Lee and this is my first post.
i am selling everything and going full time rv.I purchaced a truck.Its an 05 ford King Ranch 1 ton quad cab short bed with 6.0 power stroke diesel. It needs tires, so that is my questionj. this truck is tall and right now it has 305/55/20 tires. it looks good but the factory sticker calls for 275/65/20. We are buying a 27' prowler 5th wheel with single slide. Should i go back to factory size and what brand and rating tire should i look for? Thanks for any help and i look forward to asking for alot more help in the near future, thanks,Lee

I got almost 80,000 miles on my AT3s. Just bought a new set for under $1,000 mounted and balanced. Mine are 275/65/18. If you click the link above and go into the specs, the 305/55 are only rated 3,100 while the 275/65 are 3,700. The diameter is actually bigger on the 275/65. I'd go back to those if it were me for the capacity.

The AT3s are great on pavement, great on lose traction, the best tires I've seen on the snow that aren't rated snow tires. Not the best in deep mud as the mud doesn't clear the tires.
