Hey all, I have a 1974 xr7 and it calls for hr78-14 tires. What modern day tire would equal this tire? I was planning on putting 15" tires on the back, so i was also wondering if there is a conversion calculator or something like it to figure out an equal 15"

thanks,
Guy

This conversion chart shows that the original size equates to 225/75R14. Then, you can use this calculator to see which 15" size will work the best. Don't forget to activate the images on the calculator so you can see how the height and width of the tire varies. 225/70R15 is a pretty close match.
