Hey sorry for the delay. Things are crazy around here.

Anyway i appreciate the replies. The tag in my coach says 14,800 gross and 65psi for all the tires. 65 sounds a little low to me. The tire size is 8r19.5

even assuming that tag is accurate...a big assumption...you still don't know what you actually weigh on each axle.

brand of tire? and the complete size from the sidewall?


According to tag Gross front is 5000 and gross rear is 9800

Tires are sumihoto and just say 8r19.5 which sounded weird to me but the tire shop knew exactly what they were when i replaced these tires last year.

never have seen a tire size written that way. as for your weights...again you need to know what your coach weighs as it is loaded for travel. to do anything else is akin to whistling thru the cemetery. do as you please but you’ll never be sure.

You won't be able to get the final tire pressure until you weigh it for travel. But I would say around 75 will be the approx pressure.
As for the springs I would go with the 5000lb springs.
