Quote from: skloon on August 06, 2020, 01:20 PMI have looked all over for a sticker but cant find one I swapped the 8R tires for 225/70/19.5 and wonder what pressure I should run them at
Quote from: ClydesdaleKevin on August 07, 2020, 07:49 AMSomewhere on the tires you will find the recommended air pressure from the tire manufacturer. Every tire made in modern times has the recommended PSI somewhere on the tire. For stock 19.5 8r tires, the pressure should be between 80 and 110 psi.Kev
Quote from: Ericb760 on August 09, 2020, 12:51 AMThat's a 30 psi range. You've been out and about. What psi works best for you?

Quote from: Eyez Open on August 10, 2020, 08:57 PM110 psi max pressure @ 3970 max load...i just happen to have those tires. A note here however...my tires are 225 75 19.5...they carry about 400lbs more total capacity..
Quote from: penskepartyof4 on August 11, 2020, 03:08 PM Could I ask here? Has anyone switched from 8r19.5 to 225/70/19.5 and seen anything good about doing it? Is there a benefit with AH11 vs AH35? Other than paying more?I am considering something by Cooper. We have good luck with them on heavy cars.I need to order tires. I have super old ah35 hankook 8r19.5 on now. They seem to be good brand and durable. I dont know the difference since this is my first RV. We are planning a boondocking trip in a few weeks and need new tires. I need to order now to make sure I am a week early on the install with no issues.

Yes I realize the topics old. 89 chieftain 33ft 454 with 128000 kms Wheels will work fine. I have been on that setup for 15 years now with my 1976 Executive on a Dodge M500 chassis (2nd set of tires). Like I stated in my earlier post the tires are a bit shorter which will make the engine rev a bit higher at cruise speeds. If you have an overdrive it is not an issue. Before I installed an OD transmission in mine it would run at 3100 rpm at 65 mph and cruise all day. I would never go back to 8R tires. The 225s handle so much better. They are also available anywhere, which is good because I do not carry a spare. I know I am gambling there, but after owning this coach for almost 30 years I have never needed one so I chance it.I assume the rims do not have to be changed out just replace tires from 8r19.5 to 225/70r19.5 correct?I have to pull mine out of pole barn storage soon. Scared to see how it made it through the winter.
