Ray,IN Posted December 27, 2014 Report Share Posted December 27, 2014 docj, On irv2.com there is a crowd that insist everyone should inflate tires to tire mfgrs. load/inflation charts which display the minimum recommended pressure for the corresponding load. The referenced pdf flatly states those charts should only be followed IF it is at or higher than the RV mfgrs. placard requirement. Trailer tires should be inflated to sidewall maximum according to nearly all trailer tire mfgrs. Carlysle ST Tire's warranty used to state the warranty was voided if run at less. 2000 Winnebago Ultimate Freedom USQ40JD, ISC 8.3 Cummins 350, Spartan MM Chassis.

oscarvan Posted December 27, 2014 Report Share Posted December 27, 2014 I guess I've never seen a debate about using pressures below the placard levels; most of the RV forum discussions that I've read are with people who insist tires should be filled to the sidewall maximums. In the case of my MH, I'm running about 10 psi above the placard pressure to account for our load as weighed. Are you saying you're seriously overweight (as in 6% or more) and compensating by over inflating your tires?

docj Posted December 27, 2014 Report Share Posted December 27, 2014 Are you saying you're seriously overweight (as in 6% or more) and compensating by over inflating your tires? Not at all. The placard calls for inflation pressures of 100 psi (front) and 90 (rear) which may have been sufficient for the coach as delivered. With the weight we are carrying, my Michelin dealer and I calculated that the correct pressures should be ~110 (front) and 100 (rear). The tire sidewall maximums are 120 psi; so I am nowhere close to over-inflating them.

Jimalberta Posted December 27, 2014 Report Share Posted December 27, 2014 Joel I am running the exact same pressures in my coach. This is based on axle weights. Havent been able to do individual tire weights yet. <p>....JIM and LINDA......2001 American Eagle 40 '.towing a GMC Sierra 1500 4X4 with RZR in the rear. 1999 JEEP Cherokee that we tow as well.

rstrahan Posted January 5, 2015 Report Share Posted January 5, 2015 As this started with Michelin tires, my 2 cents: every Michelin tire I have ever had, even with proper maintenance, came apart before the end of its tire life. Will never buy them again. Link to comment Share on other sites More sharing options...
