Tire pressure check

[luvrbus]

When did GM start using aluminum roof brows ?,Prevost rust too they have a lot of steel in those ,buses don't use S/S in high stress areas like the engine compartment and other places and from the belt line up they are steel lol most buses use the Eagle frame design now.

Back to our normal programing tire pressure all the tour operators like my friends at Arrow (300 buses) and GreyHound run strictly by the data plate provided by the manufacture,the radial tire design air pressure doesn't affect the foot print if kept in the maximum and minimum range.
Regardless of the charts tire manufactures will tell you a fully inflated tire will wear and last longer, truckers never adjust the pressure on their tires for weight when installed it is what it is and they get over 100,000 from a set . Add a little 15/40 engine oil that could help

I was going by the weight/pressure chart, but tire shop said those pressures are too low.  I was only running 75 PSI in some tires.  I now run them all at 95 PSI.

I had a tire blow the sidewall last year and the tire shop said it may have been caused in part but the low pressure.

This is beginning to sound like another "what oil should I run in my engine" thread!

Too many issues with rust falling off and causing leaks in rear tires from running over it.

5000 Comedians out of work and this guy is trying to be funny.  

Eagles don't rust...much! :-)

Your tire shop isnt going to know better than the manufacturer.

I  would agree. The tire manufacturer is the one that is supplying the warranty and thus footing the bill for claims,  not the tire jocky.

At least this is an easy fix. I'll be lowering the pressure all around to more closely match the chart, of course with a little bit of a buffer for all the crap that will end up on the bus by the end of the summer.

you guys are funny every Michelin tire I ever tried to get warranted they all tell me wrong air pressure (low) caused the tire to blow.

Honestly, I've never tried to warranty a tire accept a few that were under a road hazard warranty, but that is thru the tire shop and not the manufacturer.  I don't imagine it's any easy task trying to get ANY tire manufacturer to accept responsibility and warranty a tire.

Your in house warranties are better than a manufactures warranty anytime,Discount Tire is the only place I can find that will warranty trailer tires but they charge 10 bucks more a tire and worth it no questions asked

Walmart does road hazard for 10 ea but I don't know if that applies to trailer tires. Last set of trailer tires I got at discount tire, and I did get the road hazard on them. Turkies tried to charge me for putting in nitrogen which i never asked for. I said you need to take that off the bill, he said but the nitrogen is already in there. I said take it out then. He left it alone and took it off the bill lol.

Always interesting to see how different people interpret the information.
- I used to think the manufacturer's recommendation to replace tires at 5 to 6 years was just to sell more tires - then I experienced first hand several age related failures.
- I have also run the lab tests & seen how that compares to the real world data -AND- then there is what marketing published as results.

Bottom line - gather as much information as you can & make the best decision you can for your needs.

Everyone should take timeout and visit the proving test grounds for tires,I been to Michelin in SC,Cooper outside of San Antonio,BridgeStone in west Texas,1 in Yuma for Toyo and the old Ford testing grounds in Yucca Flats not far from me.The last time I was at Yucca they were testing motor cycle tires that job they can keep lol most of us have 8 tires no way would I test motor cycle tires     
It amazes me the torture they do to a tire to try and destroy a tire at those places

I've been digging around on our same old GMC since April of 1979 & I'm honestly saying that there is no rust on the old girl, that's my story & I'm stickin' to it... :-)

When I had a motorcycle shop...my insurance wold not let me sell or touch tires.
You got to sell a lot of tires to cover that nut.
