Was fitting some new conti 4000s 25 mm tyres to new wheels last night and have come across a problem of about 4to5mm of tyre run out. It's that much that it's hitting the brake bridge.
tried taking the tyre off and reseating it.. No difference
Marked tyre at high point and swopped it onto another rim and still same.
So then put used conti on new rim this has 2mm run out and does not touch the brake.
Thinking I will send tyre back but has anyone else ever come across this as a tyre going up n down even 2mm can't be good for high speed handling ..
What is acceptable?
