Hello all,
I bought my first 2002 Caterham 7 SV last week and have some tire questions. It only took 41 years to pull the trigger....
My wants are for a daily driver, not a weekend warrior. I live on the California coast so I have lots of options...
Currently the car has 7"x15" wheels in front and 8"x15 rears running Avon AC B10s 195/45-15 78V in front and 215/40-15 78Vs rear. The tires are 7+ years old. The speedometer is displaying my driving speed around 10 percent high. Speedometer indicates 62 MPH, actual is closer to 55MPH for example.
Questions: Where would I find out what the stock wheel and tire sizes?
Where/how does 7s read tire speed for the speedometer?
Would having 195/45s and 215/45 in back help fix the speedo error?
Any comments/recommendations would be appreciated
thanks
