Tire Resurfacer pulley sizes?

Home making a Tire resurfacer with parts around the shop, and the only thing I don’t have are the pulleys, my question is what size pulleys are needed for 1/4HP motor to turn the correct RPM to grind tires. Thanks in advance .
Mine has a 2" and a 10" pulley---I think it is on a 1750 rpm motor---pouring outside or I'd run down to the shop and check the rpm

The motor needs to be 1750 RPM first off. Seems like I've read the ratio should be about 3.5 – 4.0. Are you going to use chain or belts? If it was me I'd use chain.

Mine had similar sizes .
I actually I was wrong on the motor it’s a 1/2 HP and turns at 1725, I am planning on using a V-belt design just something cheaper than buying one


6 rear 1.5 front on a 1725 , had a 12 and 2.5 and wanted a touch faster went to the 1.5, i wanted smaller pulleys. Old ratio was 4.8 , new ratio is 4.0
