SORRY tyres again !!!!!!
Discussion
I have a Tuscan conv 2 with 235x40 on the front and 245x40 on the rear. These were the sizes from the factory. Do I keep to these sizes as there has been a lot of talk of changing the fronts to 225?. Secondly is the make of tyre Goodyear,toyas,bridgestone or verdestiens very confusing. I'm not looking for a cheap tyre just one that works good with a Tuscan. All coments welcome
Ok, lets get some actual facts down about tyre sizes shall we?
The latest Factory Sizes for 18" Spiders:
Tuscan Mk1 and Mk2: F 235/40/18, R 245/40/18
Tuscan S: F 255/35/18, R 255/35/18
225's were fitted to early Tuscans by the factory but they were later changed to the above sizes. The only T-cars that maintained the 225 fronts were the Tamora and T350 which have different geometry to the Tuscans.

225's were never fitted to Tuscans by the factory so not sure where use of this size came from? The only T-cars with 225 fronts were the Tamora and T350 which have different geometry to the Tuscans.
Except that the original front size for 18s on non-S Tuscans (like mine) from the factory was 225/35 x 18. They changed to 235/40 in early 2003 when they swapped from S02s to Toyos from memory. The rears went from 255/35 to 245/40 at the same time.Factory Sizes on 18" Spiders:

Just to add some more actual facts.

I'm sure the OP is very pleased with all the ramblings about Mk 1's, Red Rose, and 'S' spec cars, but he was after advice on the tyre size for a Mk 2, non-S spec Tuscan convertible running 18' wheels.
As above, the original factory tyre size for your car was the 235/40 front and 245/40 rear which was what mine came with. Since the last set of Goodyear GSD3 spec Eagle F1's wore out, I've replaced with a full set of Goodyear aysametric Eagle F1's sticking with the 235/40's at the front and going with the 255/35 'S' size tyre at the rear. I was tempted to go with the full 255 tyre all round but have heard reports that it results in awful tramlining.
I've not noticed a huge difference other than the new spec Goodyear's are much better in the wet, they cut through standing water much much better than the old GSD3's.
Hope that helps
Paul

Thanks Paul I was wondering weather to go for 255 rears as per the S spec and keep the fronts the same. I think the tyre make is just as important as how the car performs,so I'm going to look at the bridgestone and pirreli route because Im not keen on the goodyears . I think having quite rare cars there is not a lot of feedback on what makes suit the cars so renewing tyres becomes a nightmare!!!!!!!
