[CTPATRIOT]

I'd like to get some mounted 20" Turf Tamers for my "82 R.Can you guy's recommend an exact size I need and a good place to get them?Thanks

What size do you have on the R now?



Never liked Turf Tamers.

20X11X8's on factory steel.They have "form a gasket" between them now and leak.I was thinking just using tubes with new tires?How were these sealed when new?
