Tyre Temps & Handling (156 & Toyo Proxes)
A couple of months back, I bought a new set of four Toyo Proxe T1-S tyres for my 156 (16" TDs, Sportpack Suspension), since the old Firestones were worn. Since then, the back end has felt pretty "twitchy" and the whole car seems to be more affected by crosswinds (yeah, I know, sounds wierd).
At first I figured it was just the new tyres taking time to "wear in", but I've now done a couple of thousand miles on the tyres and things don't seem to be improving.
Cornering causes a strange feeling; the front end seems to go exactly where I point it, but the back seems to take a moment to "shift" into position, giving a disconcerting feeling like the back end is about to break away. It never does (not even any tyre squeal) but then, at the speeds I'm talking about, I'd be shocked if it did.
To top it off, I spent the weekend in Edinburgh, driving back last night, and was shocked to find that, despite a long, high-speed motorway run (M74-A74-M6-M55 - about 130 miles), the tyres were stone cold to the touch when I got home. Granted, the temperature last night was bitterly cold (ranging from 0 to -6°C over the course of the journey), but I would have expected *some* residual heat in the tyres.
So, two questions, possibly related - unusual handling since I put the new tyres on (don't recall anything similar on the old tyres... although I might have been sensing it and writing it off because I knew the tyres at the time were old...), and stone cold tyres despite a long trip.
