What sort of tires would you suggest?
what are the largest tires the rims can take?
Thanks
When I was 145 lbs riding with 15 lbs of gear 28 mm worked fine. It matters how much weight is on the tire as well as the road type. If you’re above 175 lbs or carrying 25+ lbs on the rear wheel I’d suggest 32 mm if the frame has room. I prefer a heavier tire on the rear with strong sidewalls if there’s a moderate to heavy load back there since riding through rocky spots can damage a light tire sidewalls that’s heaviky loaded. So 32mm is a reasonable upper limit for the rim. I’ve put 35 mm on 13mm inner widthrims and it feels weird in turns, Back in the 80’s I saw people with heavy loads on 25 mm tires and it was nuts.
If in doubt ask your local bike shop.
