Question on Michelin XL's (SIDEWALL WAVY)

[Lex_Ordo]

My 11.00R20 spare has the same sidewall, and when I bought my trailer it came with 6.50R16's that were very narrow and also had the sidewall waves. I though the trailer's tires were bad so I got rid of them.
Then I bought the duece, and found out that the tire is manufactured this way.

Yeah, he hasn't a clue. I've found that about 40 psi is about right for good ride and best tire tread wear on my U-1300. (probably near equivalent to an M35... 14,000 lbs on 4 wheels, 14.5 x 20 Mich XL's).

I have had them down to 15 psi for rough or soft stuff and never a debead. FWIW, I ran them at 60-65 psi for about 5000 highway miles and wore out the middle of the thread. That was way too high pressure. You should see noticeable sidewall bulge, and if the tires don't heat up on the highway then you are not under inflated. Michelin's 'secret' is to make their sidewalls flex well.

Thanks guys, I feel a lot better now. What do you think I should run for a PSI? The same tire guy said 100 because anything less would spin the tires on the rims.

You guys are right. What does a guy who has been the number one tire and alignment contractor for STOP&SHOP trucking for over 10 consecutive years up here in NEW England know about tires!

There's a huge gap between 1) a "friend that has a cage and works on truck tires", who somehow does not know that every Michelin XL has wavy sidewalls, and 2) the "number one tire and alignment contractor for STOP&SHOP trucking for over 10 consecutive years".

Guess that's why we have a forum where opinions are asked for and expressed. I'll stand by my opinion.
