Tyre Cross Refernce Chart

Posted on

One of the most common questions that we get asked is, "what is the radial change over size for my current tyre size".

In some instances there are multiple options, in some cases just one or two but vary rarely is there nothing. 

Tyre sizes can be a bit confusing, as the size designations changed a lot over the years. From standard cross ply sizes such as 6.70-15 to Alpha Numeric sizes like F70-15, all the way up to modern P-Metric sizing, such as 205/75R15. Even the most savvy car guys have trouble decoding certain sizes, so take a look at this handy chart, and it should help you figure out the bias ply and radial sizing cross reference!
