When I ordered my D300 HSE, I specified 20 inch wheels. I noted that summer tyres would be fitted. I informed the sales rep that I would be replacing the summer with all seasons tyres. The rep said he would arrange to have the new tyres fitted for the hand over.
When I was notified my new car was on it's way, I asked the dealer to confirm the tyre size. He told me 255/55R20. So I purchased a set of tyres and they were fitted by the dealer on the day I collected the new car.
My question is this. I got a message from the TPMS the other day that one of the tyres was a little soft. So I stopped at a local garage to use the air pump. When I checked the required pressure on the info plate, the 20 inch wheels were listed as 255/50R20.
So is there any potential risk from having 255/55R20 tyres fitted instead of 255/50R20 tyres?
I've not noticed any instability or problems with braking or cornering. The fuel consumption calculated by the trip meter is almost the same as a brim to brim calculation after filling with diesel.
I'd appreciate any insight on my situation.
Thanks.
