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...
In a GY Marathon the 225 is only 1-1/4" taller. That would only raise the trailer 5/8". A 205/75/15C needs 50psi for a max load of 1820lbs. The 225/75/15C also only needs 50 psi but gives you 2150lbs. On Tirerack the 205 is $86.00. The 225 is $89.00. Seems like a good deal to me.
Only issue is your rim width. 205 needs 5-6.5". 225 needs 6-7". Of yours are 6" then you'd be good to go.
