I am upgrading my oem starfish wheels to 20 inch targa niche wheels. I decided to go for 285or295 / 30 R 20 for rear tyres. However I could not decide for the front tyres. I always think that oem 215/45/18 stock 360 and 225/35R19 very poor for F131 chassis. According to tyre simulator I should go for 235/30R20. I want to go for 245/30R20 front (oem wheel offset is 31.5 where the new wheel has 35). Did anyone exprienced 245/30R20 as front tryres without changing car geometry (height) or without using spacer? Cheers. HK.
