Kevin, thank you for the post, what I had hoped to do was illustrate there is much more to tyre purchase than just a brand name and price. In the two major world markets manufacturers are now obliged to proffer more information. You raise good questions regarding the speedo running perhaps a tad out. Well to use an extreme example going from 82% to say 40% aspect (without upping rim diameter) would have a dramatic impact on speedo accuracy and would contravene regulation in europe for sure with regard to required speed indicator accuracy. And then the Insurance companies jump in and say 'modified but not declared' and decline claims. You are correct load and speed ratings are vital for safe sustained operation, luckily the modal cars using the tyre sizes in discussion have progressively put on weight so it s now very hard to find tyres which do not have the cars of the 60's/70's and even 80's already within their performance limits, but yes most important to check, even if you never do go over the speed limit, as Insurance companies will again use this as a lever to avoid a claim. If I may make a few more comments for Peter though, In europe a 'new' tyre when supplied must not be unreasonably old. Here we are within our rights to reject a tyre offered with a date code showing it has been on the shelf for too long. Depending on manufacturer they suggest from 4 years old you should be replacing tyres regardless of apparent condition. Be wary, there are many new tyres out there which are very old. We buy huge numbers of tyres annually and now specify no more than 6 months old at our first usage - that may be a bit harsh for a retail expectation, but illustrates the point. And finally, the major 'quality' brands generally give the best holistic price verses consistent performance and longevity. Best of luck with your selection.
