Tire Sizes - help needed

Its time for new tires - 1967 F100 Styleside 240,

The current tires installed by the previous owner are 245/60/15. They are mounted on 8" rims. They appear a little small for the wheel opening (but I can live with that).

Finding this size is really hard. I did find 255/60/15 BF Goodrich Radial T/A for a good price. Would these fit on my current rims?

The speedometer right now is dead on. I would hate to change sizes and then have to get the speedo calibrated.

Any suggestions would be appreciated,

Thanks,

Mike

Most trucks are probably running 235 75 15s, 255 70 15 is about the same height with a wider tread.

Sure the 255 60 will work, but might still appear small in the opening, but will be a little taller that the 245s.

Get away from the 60 series (low profile) tire if you want it to look taller. Go to a 75 series if you want a taller tire!
245/60/15 = 26.5" tall
255/60/15 = 27" tall
235/75/15 = 29" tall

I always use 235/75r/15 size on my F 100 models, i use to run 700 & 750 15 size back in the bias tire days, and that was a pretty good cross over size. i think you cant beat the radial ride.
