have a heck of a time getting my tire pressure the same in tires on the same axle. I have the Crossfire system on the rear tires that maintains a balanced pressure between the inner and outer tires, but cannot seem to get the pressure on the driver’s and passenger’s side the same.

I saw a reference to the Vulcan Tire PsiClops XL180 RV/Truck Tire Gauge in another thread and ordered one in the hopes it will give me a balanced tire pressure from left to right on the same axle, while actually filling both sides at the same time.

My question is, does the RV have to be on a level surface to ensure the tire pressure is in fact the same on both ends of the axle? My driveway (where I normally do my checks before a trip) slants toward the driver’s side, at a fairly good angle. In my mind the RV leans toward the driver’s side effectively placing more weight on the driver’s side. Will this affect the tire pressure when I check and adjust my tire pressure? Thanks…

Sounds plausible. One way to find out is take a reading with it in the normal direction and then take a reading after you have turned the RV around. Then you'll know for sure.

A pound or two difference is insignificant in a tire with 80-110 psi.

A slanted coach does indeed shift some weight to the downhill side, a few percentage points maybe, but whether the tire pressure changes depends on how much the tire deforms under the extra weight. It gets a tiny bit flatter, but the sides bulge to compensate, so the overall change is pretty small in most cases.

Good luck with the pisclops! Bought one and has never worked right. Says guaranteed a lifetime but called them for 4 weeks and left messages, sent 100s of emails and absolutely no response from the company. Save your money and avoid the company!!

the short answer is that the attitude of the moho will not make a detectable difference in tire pressure.

i like my psiclops a lot.

Ron,

Did you purchase from Vulcan Tire? Mine arrived yesterday, have not tried it yet as our RV is still in the shop for the rear jack leak. Just curious if you were dealing with the seller or the manufacturer on your problem.

Dan,

Thanks for the feedback, hopefully I will be satisfied with mine as well. The idea of being able to fill both tires on the same axle is appealing, and knowing the pressure is balanced and the same is a plus.
