Michael, sorry, but you're wrong on that. 308s with 16" wheels had as OEM size 205/55-16's front and 225/50-16's rear -- even with a euro spoiler. The 225/50 fronts with 245/45 rears are a common "user upsize" -- I've done that to my car. Keep in mind that those upsized combinations keep the overall diameter almost identical to the original's... having no effect on car height or potential damage to a euro spoiler. What you're adding is WIDTH, i.e. more rubber on the road.
Here's a snapshot from my Excel spreadsheet for Tire Size Calculation that makes my point more clearly about how you can change aspect ratio to get width without intentionally changing height much. And in fact, as you can see, the OEM size of slightly narrower tires are actually barely TALLER than the upsize you suggested, not the other way around: Image Unavailable, Please Login
Ditto. Same sizes as Barcheta. They aren't bad in the NW rain either. Good grip and slightly better treadwear rating than S03's. They were rated within 2 to 3% of the Bridgestone S03's on the street and 4 to 5% on the track. S03's have a 220 treadwear rating and Yokohamas are 280.
I have done a fair bit of autoxing and hard road driving and wondered what you guys/gals with a lot of tire experience behind you thought about the Tire Racks Max Summer tire comparisons. In my last three tire purchases, I have gone with the so3 twice and the goodyear F1, staying with the then current top pick. The F1 has lasted longer and feels a bit more Precise in steering imput/output and is about even in the wet. But without doing the tests back to back with new tires it is always hard to have a subjective, (and time distanced) assesment really be accurate. So, I see a lot of opinion favoring the Michelin Pilot Sport, mostly rating the MPS higher than the so3 or the f1. What are your thoughts on the accuracy of the Tire Racks Max Summer ratings??? feeble, inquiring minds would like to know, chris
