Will I notice the difference in wheel size?
I have Sportline 18" wheels on standard 255/45/18 tyres. standard pressures of 36psi rear and 44psi front (or there abouts)
I'm thinking of changing to Supermetal Cell 20" with 255/35/20 tyres.
This gives me the same radius, circumference etc, so the speedo will be the same etc.
The only difference is the depth of the side wall, which will be 1" less on the 20's.
I have STX coil overs on the van and I am very happy with the ride comfort.
Will I notice much of a difference?
@BognorMotors are suggesting 36psi for 20" tyres, so I'd be trying that.
Are there any other considerations when running 20" wheels? Fuel efficiency?
I can also get the Supermetal Cells in 18" with standard tyre size of 255/45, so really not sure if any benefits other than aesthetics for the 20's?
the 18" cells are ET40, so will stick out a little further than standard (which will be a good thing) (
I think the sportlines are 8J 50ET?)
the 20's would poke out 18mm more than standard, which again would be a good thing.
so it all comes down to that 1" tyre wall height difference and whether or not it will adversely affect the ride quality?
