Hey all, Since we're on the subject of tires and proper pressures, I wanted to ask a question of the tire experts. On my van I have Michelin XZX tires, size 185 R 14. All the information I have is from what's printed on the tire sidewall. It says Max Load is 1540 lbs at the Max Cold Inflation Pressure of 40 psi. I can find nothing on the tire that refers to a load rating (like passenger car or light truck) but there is a marking that says REINFORCED Radial. Now, I assume then, that the Reinforced marking indicates a light truck/reinforced sidewall tire? Also a question regarding the load rating, the 1540 lbs is at the max pressure. Now obviously the load rating goes down as the pressure goes down, but I was curious as to whether the relationship is linear or not? Probably not, but just checking. I know mdstockr can help here :-) In addition, here is the information that I obtained from the tire pressure sticker in the doorjamb of my 1981 Vanagon Westy. The information probably doesn't apply to you unless you have an aircooled Vanagon Westy. Tire Size Pressure, Front (psi) Pressure, Rear (psi) --------- --------------------- -------------------- 7.00-14 8 PR 33 48 185 R 14 C 6 PR 38 55 185 SR 14 Reinf. 33 40 I assume by my tires, I should go by the third listing, for the reinforced tires. That is the pressure I have them inflated to now, 33 psi front and 40 psi rear. Could someone decode the tire size/ratings above, mainly the first and second ones? What's the PR about, does that mean passenger car tires? All help appreciated, Sean -- ***************************************************************** Sean Bartnik "Life is tough, sbart7kb@www.mwc.edu but it's tougher if you're stupid."
