Default Bought New Rear Tires (8) for my T/C

My rear tires were far from being worn, lots of tread left. But they were 2004 mfg date, and I am pretty sure original to the 2005 chassis. They were Bridgestone, and were getting some quite visible sidewall cracking near the bead area. I only bought mine earlier this year, so this was one thing I have been wanting to do, even though I put about 5000 miles this summer on the Bridgestones.

So to avoid any potential road blowout, or body/wheelwell damage, I bit the bullet and got 8 new rear tires installed last Friday. Purchased General S360 model, made in USA, 11R22.5 size. Mounted and balanced, tax and all new valve extensions came to $3300.

I previously had upgraded my fronts to 315/80R22.5 to get back some safety margin on the front axle loading. The original 11R22.5 were actually overloaded past the max load. I have 14,600 lbs on front axle, and 20,600 on both rear axles. The ironic thing is the rear tires are so underloaded, about 40% of rated load. I may have been able to run the Bridgestone tires longer, but did not want to take the chances. I like to run around 70-75 mph and feel better with the new tires. Although my wallet does not feel better Oh well, gotta pay to play

Yeah,I did the same thing with our trailer this spring.
6 tires were expensive, but a blowout on the road would've been worse.

I need to replace the rears on mine (4) - they're aged out by most standards & opinions, but show absolutely no signs of cracking or wear.

I replaced my steer tires 2 years ago because they were showing some pretty significant signs of vertical fractures. I replaced the steers with Michelin XZA2's.

Ive been using 303 Aerospace Protectant / UV blocking spray on the tires when we park outside & and i don't cover the tires.

Bush, who stocks the Aerospace protectant? I need some right now, as mine sits outside as well.

I also use the 303 protectant. Not sure it is really that much different than others, but it does claim to offer UV protection. I have some plywood covers I use to shield my tires when parked at home.

I bought a gallon jug of the 303 off amazon like Don suggested, and refill an old spray bottle. The 303 is not a super glossy finish, but it certainly is somewhat shiny. It is a lot like the old Armor All, not the low-gloss AA. In fact the 303 is a white watery liquid, just like AA.
