I know the topic of tire sizes and speedometer error has been going back and
forth for some time now but I have a few questions on the topic. I recently
purchased some new 16" Panasports and would like to put on some high
performance tires. I did some quick research on the tire sizes and the
speedometer error that I will encounter with each size. Basically from the
numbers I should go with 205/65R16 or 215/65R16 to get the closest numbers.
The problem is there is a very limited (ie I didn't find any) high
performance tires in this size. I did find some high performance tires in
the 225/60R16 size, but I believe they are too wide from what I've been told
which is disappointing in that they are nearly the exact same size as the
stock tires. If I drop down to 215/55R16 there are a number of choices and
pretty much where I am leaning at this time. Again, the problem is these
tires are about 5% to fast so if my speedometer said 60mph I would be
traveling at 57 (theoretically. I know the tire pressure and other factors
aren't figured in). This isn't too much of a problem as my truck is about
5mph faster than the speedometer read since the tires are larger that stock.
All this said, I am curious to know how difficult it is to recalibrate the
speedometer, if it's possible to do at home, and do they make some kind of
calibration box for this purpose (I want to use my stock speedometer).
Also, are there some high performance tire options out there that I haven't
found?
Now if they had 17" Panasports.
Thanks,
Adam
