I had to replace two front tyres yesterday on the XK8. I wanted to match the tyres that were already on GoodYear F1 GS. They are now a discontinued item so I "saved" $92 on list price but they were still expensive. Anyhow, I wanted to pass on that GoodYear has a new 3 Year Alignment Program where for $199 you can have an alignment every 6 months or 6,000 miles for 3 years! Just wanted to pass it on here. Cheers!
