205/75/15
I’m thinking about increasing the tire size from a 205/75/15 to 225/75/15 on a 2001 Jayco Quest. Has anyone increased to that tire size? Are there any benefits? Any recommended ST tire ply...

I have increased Tire size on our Funfinder 244RBS.
Was 20575R14 to 215 /70/R14
The plus
Had two blow outs with the old tires at about 12,000 miles that had a load rating of 1400lbs the new tires have a load rating of 2250lbs.
Tire pressure can be increased from 50 to 65psi, we have set ours on 60psi.
Stability appears just as good. Hopefully a bigger footprint so will help towing in the sand.
The Minus
Clearances are a bit tighter.
Brakes were lousy bigger tires need more braking power, Fixed up a voltage drop issue was 8 volts now 11 volts they work much better.
Fitted shock absorbers at the same time.
Next job....rewire from brake controller to get better voltage at the brakes.
Plus install the Tuson Electric Sway Control.
