was8v 0 Posted October 22, 2007 I have some 195 50 15 Yoko A509s lying round and the Corrado VR6 needs new boots. Has anyone encountered problems running 195 50 15 rather than 205 50 15 tyres? does the 10mm tread width and speedo reading 1.7% too slow make any difference? The rims are standard BBS solitudes, 7x15". Quote Share this post Link to post Share on other sites
Yandards 0 Posted October 22, 2007 I would say that difference in rolling radius is within an acceptable tolerance, after all the VR has the same gearbox output ratio as the other Corrados and they run these size tyres as stock. As for if it will be ok, you might find that the reduced track means you need to put some air in the tyres but otherwise it should all be ok. Quote Share this post Link to post Share on other sites
dr_mat 0 Posted October 23, 2007 I don't think you'll notice the rolling radius difference, it's tiny (compared to e.g. the difference between new and worn tyres). The other issues: clearly you'd have slightly less grip; and the tyres would need to be rated at least "86V" weight rating to support the front end of the car at 150 mph safely.. You may get away with it, since yours is an 8v converted to a VR, but if the log book said "VR" you'd really be better off running 205s, for MOT test sake if nothing else.

was8v 0 Posted October 23, 2007 the tyres would need to be rated at least "86V" weight rating to support the front end of the car at 150 mph safely.. Hmmm I'm never going to be doing 150mph.... but a good point the yokos are 82V You may get away with it, since yours is an 8v converted to a VR, but if the log book said "VR" you'd really be better off running 205s, for MOT test sake if nothing else. Thats news to me! The cars always been a VR6.... If theres likely to be an MOT issue then I'll sell the yokos and source some 205s. There must be lots of people running 195s on aftermarket rims incorrectly... Cheers for the input! Quote Share this post Link to post Share on other sites

Ah, was just your forum name "was8v" I assumed that meant something .. :) There's lots of people running questionable tyres all over the place, but that doesn't make it a good idea! ;) Quote Share this post Link to post Share on other sites
vwdeviant 0 Posted October 23, 2007 IIRC when researching MOT after JonesMark's recent "issues" apparently the MOT states basically tyres must be suotable for teh wheels mounted to.. I.e. Stretch IS an MOT fail.... and stupid.. (All IMHO) Quote Share this post Link to post Share on other sites

chubbybrown 0 Posted October 23, 2007 185/55/15 or 195/50/15 were standard sizes on early Valver,so the Car manual says right here 8) anyway we swopped from 185's to 195's as the size is Far cheaper I got 4 pilots for £220 and you r a cosco memeber you can get them for £180 Quote Share this post Link to post Share on other sites
vr6storm 0 Posted October 23, 2007 you might find that you insurance could be null and void if you are in an accident tho..........as VW states 205's for the Corrado VR so therefore you are under tyred according to the manufacturers spec Quote Share this post Link to post Share on other sites
