205 x 55% = 112.75 = sidewall height
112.75 x 2 = 225.5 = 8.87795" + 16" (rim) = 24.87795 diameter
225 x 40% = 90 = sidewall height
90 x 2 = 180 = 7.08661" + 18" (rim) = 25.08661 diameter
As you can see, the diameter will be only 0.20866" larger, so I would say YES !
The equivalence is 225 50 R18 so that the diameter may be the same.
NO , rim size is incorrect.
Yes. I've done it. Fits well.
Yes, they can. They must be mounted as a pair.
Yes, that is reasonable
Yes they can
Yes, 235/60 R18 tires can be substituted with 225/65 R18 tires, but there are important considerations. The 225/65 R18 tires have a larger sidewall height and overall diameter, which can affect speedometer accuracy, handling, and clearance in the wheel well. It's essential to ensure that the vehicle can accommodate the change without causing rubbing or other issues. Always consult your vehicle's manual or a tire professional before making such substitutions.
They are Taiwan designed and now made in China or Taiwan. I got NS-2 and my fronts (225 45 R18) have "made in Taiwan" mark and my rears (245 45 R18)have "made in china, designed in taiwan".
