Hey all,

I was just posting this to let everyone know of a new website I found if anyone is deciding to change wheel sizes on their vehicle. The website is www.miata.net and on there is a tire size conversion chart. But for a quick reference, if your B series truck, specifically, runs 205/75/R14 you can jump to a 15" wheel and run 215/60/R15 and only be off on the speedometer about .6%. Which means if your travelling at 60 MPH according to your Speedometer, you actual travel speed is about 59.735 MPH. Hope this helps, it sure did me.

Thanks,

Mazdamazing
