Roadtrek 190 Polpular Tire

A) What does it say on the vehicle weights and measures sticker or plate, wherever that is located? Usually has the tire designation, including P for passenger, and LT for light truck.
B) Check the owner's manual for the same info.
C) My 2002 190P on the Chevy chassis liked to wear LT245 75R16 Load Range E. It weighed around 4 + tons loaded.

Unless there's a pressing reason to put passenger tires on it, I'd go with the light truck tires.

EDIT: I have used Michelin LTX AT2 and MS2 models on mine. Preferred the AT2 for the more aggressive tread design.

We use, and quite like, Michelin XPS Ribs. A bit pricey, but oh what a difference.

Cheers.

X2 michilin is about the best out there. they,ll serve you well.

“the salesman states...”

Always a “caution” sign for me.

I have used the XPS rib as well. Now using the Bridgestone R250.
Very similar highly rated tire with similar construction and tread, however less expensive and North American made!

I have had my Ford e250 based Pleasureway Traverse for 10 years or so now. Last year, for the first time, I splurged and bought the Michelin LTX tires instead of the cheaper Firestone. Hands down it was the best upgrade I have ever done on the van. It drives like a different vehicle - quieter, far more stable on the highway and in crosswind situations, better winter performance (not a winter tire though). Highly recommended.

Has it got 15" tires on it now.

Our 2007 Roadtrek 210P came with Bridgestone VSteel tires and I replaced them with the same thing. They have worked well for me but they are now to the age (7 years) where I am thinking about replacing them. No cracks and a lot of tread left but the age is creeping up on them. I will follow this thread carefully to check out alternatives. This RT has mostly been stored inside in a heated and air conditioned environment so tires really last well, but still I am not too comfortable with them at some point this year....probably before we take a long trip.

It has 15" rims now.

I bought 4 Nexen Roadian /AT2 LT 235/75R15 at Walmart in 2014 and am very happy with them. If I remember right they cost about $110.00 each.
I have had Dunlop and Goodyear before but like the Nexen's much better. No problem with sway in high winds. My van is about 6500 lbs.
