I bet a good mechanic who works in a shop with high traffic of customers would know which tires fit more generously than others.

Hi, I bought DT swiss RR 465 rims formerly known as the DT swiss RR 1.1. I tried to mount new and used Conti's and Michelin's on the rim with no success. I cant even get the first bead over, these rims are ridiculously tight! I tried blow drying the rubber, stretching the tire etc. still no success.

I am sure a bike shop can get the tires on with some special tools and lots of effort, but the bike shop wont be around when I get a flat out training. So I can't rely on a bike shop simply to get the tire on the rim.

My three types of training tires are Conti's Gatorskin, Conti's GP 4000 and Michelin's Lithon 2, I have failed with all to mount on the DT swiss RR 465 rim. I dont want to think about the possible nightmare of getting a flat out on the road... I will be stuck because its damn near impossible to mount the tire on the wheel.

My question... is there a particular tire that will work with ultra super tight rims like these? Is there a brand/make tire that runs loose that will be easier to mount? Something of decent quality?

Thanks M
