Wheel/Tyre Question

[High-Lo]

I have recently picked up KLP's old 16" Lorinsers (which I'm very pleased with) and have a quick question about tyre sizes. The wheels are 8Jx16 ET30. One pair of tyres have 225/55 fitted and the other pair have 225/50. Anyone know if there is a reason for this? If not I will buy another two to match up with the two with the correct profile.

I currently have 7Jx16 ET37 with 205/55. I'd assume that I will need 4 x 225/55 to keep the same rolling radius (unless there is a reason for having different profiles front and back).

Any advice appreciated.

Thanks,
Steve

You'd need to have 225/50 for (almost) the same rolling radius.

205/55 or 225/50 are both fine for the 202. SInce the wheels are the same width - 7", it would be a good idea to keep the same size all round. 205/55 is cheaper.

This chart might help, quite good for reference anyhow.
