Hello,

I've been searching the web without a lot of success. The tires that are on it now are R 4.00x18 and F 3.25x19. What does the collective say about new tires?

Thanks,
Al
 
Nobody sizes tires by inch anymore, there are conversion charts online. Front 110X19, rear 120 or 130X18. You need to study about the second number unmentioned here or the sidewall height as it relates to tire width.
 
Thinking that's correct, I had the 110 number locked in my head from later models where they widened the wheels a bit. 100 is a 3.25 tire and 110 is a 3.50. '79 uses the 100 front tire. Somewhere in '81-'82 the wheels widened from 2.15 to 2.50. I've used a 110 front and a 130 on the back on my '80, which uses a different wheel design but the same narrow width 2.15 as yours.
