I'm running Toyo Proxes T1R all round with the rears being the most recent addition. Unfortunately putting them on the rear has resulted in stability issues; it's like driving on Diesel but it doesn't actually lose grip. Very unnerving!
The fronts feel fine though. Bizarre!

I had my other half follow me and she said it looked like the tyres were made of sponge as she could see them "springing about". As if the tyre pressure was low.

Previous tyres were Goodyear Eagle F1s which were very stable although didn't have the grip of the T1Rs.

I like my standard rims but I reall need a good set of grippy and stable tyres that haven't got soft walls like the T1Rs.

Suggestions welcome

TIA
