NO , rim size is incorrect.
Yes, they can. They must be mounted as a pair.
The equivalence is 225 50 R18 so that the diameter may be the same.
Yes they can
Yes. I've done it. Fits well.
Can it? Yes. Should you use this size? No. Your speedometer will read 58 at a true 60 mph. Handling, performance, ride, and fuel mileage will be adversely effected. If you want to go to a 55 series tire then install size 215/55-18 which is an excellent substitute.
Yes, 225, can substitute 215 since it is width of a tire and doesn't play huge role. Also, because we are only talking about tiny difference.Know that even though you are only talking about a small difference in diameter your speedometer will be off. Another replacement would be a 225/50-18.Stock Tire - 215/55R18 |>Search Tires Tire 1 - 225/55R18Section Width: 8.46 in 215 mm |Section Width: 8.85 in 225 mmActual Speed: 60 mph 100 km/h |Speedometer1: 59.0 mph 98.4 km/hSpeedometer Difference: 0 |Speedometer Difference: 1.573% too slowDiameter Difference: 0 |Diameter Difference: 1.56%-------------------------------------------------------------------------------------------------->Search Tires Tire 2 - 225/50R18 |>Search Tires Tire 3 - 235/50R18Section Width: 8.85 in 225 mm |Section Width: 9.25 in 235 mmSpeedometer1: 61.0 mph 101. km/h |Speedometer1: 60.1 mph 100. km/hSpeedo Difference: 1.706% too fast |Speedo Difference: 0.223% too fastDiameter Difference: 1.69% |Diameter Difference: 0.22%
Doubtful, that is a big change. You can usually go one size up or down with no problem, Not three.Doubtful, that is a big change. You can usually go one size up or down with no problem, Not three.
No, it will be too large a diameter tire. Handling, ride, mileage, & power will suffer. Also your speedometer will be off.
Yes bigger ones are better for rear wheels
Yes.
Driving in the snow on 225/50/R18 is worse than on 195/60/R17, if the same tires are used.. the tire width is what matters in snow!
