which of these 3 is the best tire size for 20 inch wheels?
this is taken off heissrods post, not sure which one you would recommend of the 3 in terms of balancing performance/looks
OPTION 1
F 245/30_20|R 285/25_20 (Both 265/25 & 275/25 are not valid tire sizes, which would be closer in diameter)
Diameter: F 25.8" | R 25.6"
Using this size, your speedometer and odometer will be affected by 1.2%, or you will actually be travelling 60.7mph when your speedo says 60mph. Over 1000 miles, your odometer will read that you traveled 988.5 miles.
OPTION 2
F 255/30_20 | R 295/25_20
Diameter: F 26.0" | R 25.8"
Using this size, your speedometer and odometer will be affected by 2.0%, or you will actually be travelling 61.2mph when your speedo says 60mph. Over 1000 miles, your odometer will read that you traveled 980.4 miles.
OPTION 3
Taller size that some users run for +2 Upsize to 20" wheels
F 245/35_20|R 275/30_20
Diameter: F 26.8" | R 26.5"
Using this size, your speedometer and odometer will be affected by 4.7%, or you will actually be travelling 62.8mph when your speedo says 60mph. Over 1000 miles, your odometer will read that you traveled 955.4 miles.

thanks for reply: 20x8.5 offset 35 and 20x10 offset 35
the 1st option was what i wanted but i just found out the 285/25 tires arent available for 3 months so im not sure if i should wait or try another option

any other opinions on this? roads arent too bad here so im thinking 285/25 would be ok but there is a long wait for these tires cause its rare and i dont know is it something that if i hit one bad pothole it will def. damage the wheel/tire or is it something where as long as im relatively careful i should be fine?

is it when i hit potholes or just rolling into steep driveways? i dont plan on lowering the car and the roads are pretty good here
if i go to the 35/30 setup what tire size you recommend and what are the cons to the 35/30 setup?
anyone running either setup can chime in too as to their experience
