Unsafe at any speed....
Here's some background. Bought the RV new in 2006. It's a 294RLS Cougar tow behind 30'. The factory tires were TOWMAX ST, 225/75R15. The factory tires lasted for three years, then I changed out the ...

For me, it is mainly with the Michelin's. Both 'P' class and 'LT' class on
trucks and cars. The 'ex' got the two lux sedans and they both had Michelin's
and they were also cracking (lived at a different home, but same town)
Currently have Bridgestone Dueler Revo LT265/75R16E's on 16x10 alloys on my Sub
About 6 years with less driving than the previous Michelins.
Same PSI
Same alloys
Same town, same spot on the driveway 'outside'.
Same driver beating them up on pavement and off-roading.
Same care. Weekly wash and 303 treatment that I allow to cure before doing
anything (about 2 hours in the sun). Found or learned of 303 from
the area Michelin rep when trying to get warranty on the 3rd set of
BFG 33/12.5R15LT load range C's with blisters poking up from the root
of the tread area...THIRD SET... His first question was did I use
ArmorAll...nope and he then said to use 303, which I never heard of
No cracks of any kind, anywhere.
Now for the 1980 C10 Silverado. The Timberline 33/12.5R15LT load range C has
cracks on the tread root, between tread lugs. No cracks on the sidewall.
The Yokohama 33/12.5R15LT load range C has NO cracks of any kind. This truck is
driven even less than the Sub. Mainly for street sweeping every other week and
taking care of properties (gravel, dirt, fertilizer, wood pellets, firewood, etc)
The C10 is parked within 20 feet of the Sub and is also not garaged
Same 303 treatment, same wash every Sunday morning, same driver, etc
Odyssey is parked next to the Sub and it's Michelin's that came with it (bought
used) had started micro cracks on the sidewalls. Falken's that replaced them did
NOT crack and wore out. New Coopers have about 10K and look like new.
Live in The San Francisco Bayarea. Sun is not a problem. Three major airports
and several highways, but only the Timberline & Michelin's have cracked
Michelin's were fine till around the mid/late 90's and assume they changed their
formulation or processes, or both
First set of LTX-AT's on the C10 were fine. First set of LTX-AT's on the Sub
were fine and went 40K very harsh miles....then something happened with the
3rd set on the C10 and 2nd set on the Sub...they cracked very soon. All in the
same town, same driver, etc, etc
Yes, drive very, very hard and get sideways often on purpose just because. The
Duelers were very 'soft' at first, but they are now going or looks like they will
go farther than the Michelins
Am very impressed with the Copper's on the Odyssey and will try their 'LT' class
when the trucks need tires (not soon)
Since I go through lots of tires and have lots of vehicles... Cover a
of ground and know that this is mostly with the Michelin's
Also have played with enough tires while racing, working my way through college
as a tire monkey in one of the very high end dealers in town, designed some test
stands for DOT to test tires. We supplied the controls and used a locomotive traction
electric motor. They/we burned up dozens of tires during the certification and
acceptance testing (still have that burnt rubber smell in my nose some times)
