I have recently gone from Toyos T1Rs to GoodYear Eagle F1 Asym 2's on the rear and I'm not that impressed. They seem to grip as well but they have a sort of floaty feeling when going round a slight bend at speed that just gives you a doubt. It's almost as if its going to go into a slide but then its fine where the Toyos felt planted. Maybe because they are new? I will play with pressures and see if that helps, 24psi at the moment.

Anyone else running GoodYears on the back?

Hi. I had a similar problem. I have michelin pilots on the front & avon zzr on the rears. I believed the problem was because of asymetrics on one axle & not the other. I was recommended Matt Smith by four others here on pistonheads.
He lined up another set of rears to try & there was an instant result, but he also then did a geometry check & one of the fronts was out & others adjusted. Heres the thing- It sorted the prob totally. Previously i had been told that the geo was checked elsewhere. Matt Smith is so thorough- i was pulling my hair out with this- thought i had bought a dud.
Now i think what happens is if you have different tyres on each axle then it becomes super sensitive to the geo being out. Mine was scary over 70 now solid.
Cannot recommend Matt highly enough.
Hope this helps
Regards
Mark

A lot of reviews on tyrereview.co.uk complain of the same thing... there's a mixed bag of reviews, a lot of user scores at or above 90% keeping the average up at 89% but all the negative reviews consistently say the same story even one from a Tuscan2 driver, perhaps they represent the % who care about floatiness/sidewall stiffness, or perhaps they represent the % who bought the wrong Load rating for the tyre for their car... What load rating did you get?

Tuscan2 review:
"drive tvr tuscan s got the earlier f1 on the front which is good , the new asymmetric 2 on the rear , im immediately changing them , the sidewall is very soft which has ruined the handling ,in fact its the worse tyre i have had on this car as the roll when entering and exiting a corner at moderate pace is awfull, yokohama 255/35zr18 arriving next week,for this reason i would recommend you look elswhere i will update once i have the yokohama .

I'm looking at getting vredestein sessantas soon, because of the universal praise they seem to get.

I think this may have something to do with the mixed views, but I'm not discounting MOM's hypothesis either.

I changed the fronts first and liked them on the front but the rears are a different kettle of fish and a good deal less stable. The sidewalks are very thin so perhaps upping the PSI will fix the feel. As I say the grip is ok they just feel strange.

Interesting topic. I had always assumed that having the same type/make of type all-round was the best solution. I used to like the Toyo 'V' treads on my first Tam, but they seem to have been superseded with different patterns now, so I don't know which tyres now best suit the Tam/T350..

Also have assym 2 all round the rears are awful, give you no confidence at higher speeds as the car moves around so much, tried all sorts of different tyre pressures. Getting rid asap

should be a number on the side.
On blackcircles you can buy two variants of the assy 2's:
245/40 R18 Y (93)
245/40 R18 Y (97) XL

Maybe some faith will be returned to the brand if you say you got the (93) and WolfyJones the 97 XL.

Just trying to find some logic in the mixed reviews.

255/35/R18 94Y Made in Germany,

I believe some Goodyears are made in the Far East, you don't want them on your car.

235/40/18 95Y XL made in Germany. That's the correct size for the Tam so I don't know how you guys are getting on with the sizes above!

The fronts are fine, if anything better than the Toyos but like you say they feel like they squirm around underneath the car. Looks like that's £300 down the drain and back to Toyos then!

It also look like Toyo have stopped making the T1R in the right size for the rear of the Tam. Racing Green have them at £192 each but I'm not paying that inflated price!

Just went out to the Tam to see what was marked on my rear Asy2, shows "Made in Germany 95Y" . Am running T1 Sport fronts at 24 all round. Don't have a problem, then again I don't push it...too much.

So the same rear tyre as me. It's not so much when you push as they seem to grip ok it's more the higher speed "feel" I don't like. The transition between a straight and a bend feels like that first moment before a slide, only it doesn't break away. Maybe as the tread blocks ware they will improve.

Nope feel exactly the same as you and I have done 9k miles on them and still the same.

Its unnerving to say the least

ok, so you guys with negative views aren't on the very stiffest variant but nowhere near the lower.

Need more data to draw real conclusions, but they are out of my consideration unless more data from T car owners arrives.

Well, in truth they were already out because the negative reviews are so consistent and those users seemed to map to my sensibilities more... I'm not criticising those with noise/comfort/wear rate as a priority, its just that a direct feel + wet performance are in my priorities.

It's the usual thing with this car, an expensive suck it and see it works... if you find something that works for you stick with it!

I've never had a TVR before but 24psj sounds very low, is that normal?
