I have a 1949 3100 with some OLLLLD retreads. Time for some new rubber.

Current tire size on the recaps reads 7.75X15 on front and 8.45X15 on rear.

Truck VIN plate shows 4600# GVW and then the shop manual I have says "15-6 or 8" for that GVW. Lower GVW's show "6.00-16-6" and "6.70-15-6" for 4200 GVW, and "6.50-16-6" for 4500 GVW.

I'm confused!

I'm not going to haul much weight in this old 'bolt, just want a smooth ride for running around town...

What size modern tires would you recommend?

Thanks!
