Keep the TRX wheels and tyres for concours, and buy a set of SF 16" wheels. Even after shipping and buying 4 tyres, you'll be ahead.
TRX’s weren’t that good when they were new 35 years ago. Sent from my iPhone using FerrariChat.com mobile app
Plus just the variety available of tyres with the later wheel, without taking the lower cost into account, is worth it.
I’ve been trying to buy a second set of 16’s for over 10 years and haven’t been able to. Sent from my iPhone using FerrariChat.com mobile app
I think I'm with Greg on this one because modern TRX tyres are pretty good grip wise and I actually like the wide 220 fronts. Sure, the TRX wheel design isn't as nice as the 16 inch (campy/speedline/SF) but the TRX tyres have a nice chunky square look about them that I rather like. I seem to recall that PP's XWX on his 308 had a TWI index of 100 (am I wrong?), so the compounds are quite soft. So I'd expect a TRX tyre to be similar, hence the assumption that modern TRX's would be a good tyre to drive on. Given the kind of mileage that one does in a 308 nowadays, the tyres expiry date would pass before the tyres would wear out. Further more, finding excellent 16 inch tyre for a good price isn't that easy anymore, well at least in the 308 wheel sizes. I certainly remember it being slightly problematic finding tyres in the right sizes for my 308. The Bridgestones I ultimately purchased were't great either. Although I haven't crunched the hard numbers, my gut feeling is that buying a set SF wheels and getting tyres of a similar performance to a modern TRX wouldn't be that much cheaper over the course of an ownership experience, unless that ownership was well over a decade. P.S I had a quick look at SF website and the wheels are slight more expensive than set of TRX tyres. That would seal it for me. I'd go original.
Gee you're a troublemaker! What happened to you? You used to be a really nice guy. Did 308 ownership hardened you up
So you're suggesting that just because XWXs are incredible tyres now, that TRXs must be the same? Yes....100 TWI on the XWX, but what is the TWI of the TRX?? Curious minds want to know.
I actually don't know Peter. I tried some preliminary research last night but couldn't find an answer. I looked on the Michelin Classic and Coker tyres website and couldn't find an answer on the TWI. So I'm just assuming that Michelin would do the same for the TRX as they did with the XWX's. If TWI is in the high hundreds or 200's, then maybe the TRX wouldn't be such a good tyre. Do you know Carl? I did read on a BMW forum that someone with an Aussie E24 635CSi purchased some TRX tyres for his BBS wheels and other forum members were surprised by the pace and grip on the car on a club run. So I used this a basis for my assertions. Not scientific by any means and yes, I could be wrong.
Good god!! LOL. Well, not an expiry date but I'm just using the general assumption that one should replace tyres within 5-10 years (depending on who you talk to) of the manufacture date due to compounds hardening over time/tyres going off. Is that a myth?
Not a myth at all, but there is nothing written on the tyre and 10 years is the absolute maximum. Interestingly I was about to change the 5 year old Michelins on my 575 for the upcoming GAD run but my friendly tyre guy has a gadget that measures the hardness of the rubber and mine are still in the as new range. His comment was that UV is the big issue and, because my car spends 95% of it's life in dark storage, the tyres haven't hardened. I was very happy - they still have 80% tread depth.
Cheers. I'm sure there is a code on the tyre with the week and year that the tyre is manufactured in. Am I incorrect?
