I had to use tyres other than 205 x 45 x 17" on my V70R as the wheels were becoming expensive after hitting pot holes. though 225 x 50 fitted they rubbed on the wheel arch liners on full lock and I had to settle for 215 x 55
The speedo is OK and reading correct as far as one can say
yes ive got some for my w208. didnt want to fit 17" due to insurance etc so got the newer design 16" ones. two rims are fitted with 225 50 16 and i assume these were on the rear as the other two are 205 55 16.
im going to leave the 205 55 16 for the front but just wanted to check if the wider tyres were gonna be ok for my car and rims
