Much has been discussed about the choice of rubber on the Tuscan, but for the love of God don't ruin your car like I did. In an attempt to protect the rims from the worse of the Northern roads, I went big at the rear. A pair of 255/40 rear Goodyear Eagles totally ruined the handling of my car, to the point it was floaty at speed and felt like it wanted to steer from the back. Felt just awful verging on the dangerous.

Borrowed a set of wheels today with smaller tyres (thanks Pete) 225 at the front and 245 at the rear on some lovely Speed12s off a Tamora. Chalk & cheese.... the Tuscan performed better than it ever has, ever.



Begs the question, is the Tamora actually the best handling TVR because it has the right tyres for the T chassis?

The Tamora wheels are the same offset Keith and it has made a huge difference, it makes you think how well the Sag would handle with narrower tyres on the front instead of the standard 255's?

As for the tyre type, these borrowed wheels have Toyos front and back and I was running Goodyear F1s before. Both bloomin good tyres but the toyo don't seem to have quite the bite of the Goodyears, well so it seemed but maybe they just give a little more confidence....

I'm just realy surprised how poor the 255/40 were on the back of the Tuscan, lesson learned!

Please all confrm you have had your cars geo'd on a 4wheel Hunter aligner reasonably recently? No amount of hundreds of pounds spent on tyres will resolve a mis-aligned car. And it costs less than £100 for a geo. A Tamora owner I know had his done recently at my TVR guy's workshops, and went home with a transformed car....

A good point but not applicable to my original issue. My Tuscan handled very nicely until the rear tyres were replaced, changed worn GSD3 Goodyears in 255/35 for new deeper profile 255 Asymetrics on the rear and it all went to pot. Nothing else changed. I tried different tyre pressures and ran them for about 500 miles and they were just blooming awful!

Tried these Tamora sized tyres and it's better than ever so yes, a full geo will sort a bad car out, but it won't compensate for the wrong tyres. All IMHO

New Toyos ordered, 225/35 for the front and 245/40 for the rear, ordered from Oponeo, along with a pair of Contisport 5 in 235/45 17 for the Volvo, all for £580 delivered which I though was very good value. I'll let you know how they are once fitted.

hope you bought the T1R toyo's.
they suit the tuscan great

Nope, went for the same T1-sport pattern as tested on those SP12 alloys. Hopefully they'll be as good as the T1R.

Cheers

Just a little update on this, dropped off the wheels and new tyres this morning at the wheel refurb company (Alloyfix in Westerhope, Nr Newcastle) and got a call later indicating that three of the wheels were buckled which may explain the mild vibration at speed.

They're going to straighten them before re-finishing them and fitting the new Toyo's.
