I think that if it wasn't for the VX the 175 bridgestone would never have come into existence.May i ask please?
![]()
Did vauxhall or lotus (whoever chose the bridgestones) make a mistake then? I know (or think that i remember) that thinner wheels/tyres were introduced on the fronts to dial-in a healthy amount of understeer. Is it that understeer that you are trying to eliminate? Why was it that they made such a fundamental mistake then?Is not the rigidity of the side walls an important part of the stability? Was their choice of the best all round compromise tyre of bridgestone so very wrong?

If putting 195/45/17 front tyre was the wrong thing to do .someone would have put something in the threads .As for the insurance ( WELL )I would also be careful about fitting other than OEM standard tyres (i.e 175/55/17) to the original rims unless you're going to tell your insurance co. If you had an accident and they choose to inspect the car I would put money on them checking the tyres. Could suddenly find yourself in deep doo doo.

Not trying to be mean....
I would phone your insurance before fitting them. An acquaintance of mine is an insurance assessor. His employer will always attempt to reject claims (and invalidate insurance) if the vehicle is no longer std. Fitting deacals, non std steering wheel or roof box are typical excuses for rejecting claims.
If your insurance company is happy for you to fit 195's on 5.5 wheels then please let us know.
I don't think any of the 16/17 guys are trying to be clever with their replies, it is just a matter of airing their best advice.

I am sure there has never been a new car sold in the UK that has used the combination of 5.5 inch wheels and 195 tyres. Certainly not a performance car. If I am correct there will be a very good reason for this.

It also helps to show that 195/50/17 would be a far closer match to 175/55/17 than 195/45/17. Also that the rimwidthulator is OK with 195/50/17 on a 5.5 inch wheel. It's all approximation anyway but the option is there.Look here
Very interesting and should answer your questions on sizes etc.
Particularly the "Too wide or too narrow" section. There is no mention of problems oversizing/undersizing in relation to tyre coming off the rim, however does mention about handling. Interesting.

Just had a look on the sight lot of reading .But seems that as long as you dont go bigger than 20mm bigger than standard its OK.

Just spoke to my insurance company regarding the fitting of Kumhos on my front standard rims. (Admiral multicar policy)
My premium would go up by £65 as it would be classed as a modification.
Regards Mike.

Indeed. Weren't they made/designed specifically for the vx.
I think that if it wasn't for the VX the 175 bridgestone would never have come into existence.

There's 2 thoughts about the understeery nature of the VX220
1. Vauxhall (and most others) cars have understeer for safety in order to protect the general public who bimmble about in their cars. i.e. like 99% of the driving population - passed their driving test then go from A to B for the next 60 years. So, expecting their customers to mainly be Vauxhall-ish they dialed in understeer. I wonder who the Vauxhall/Opel test driver is and what his credentials are. Must be a soul destroying job testing the Corsa has adequate understeer.
2. The Elise S1 was set up by Lotus to be a road legal track day car then sold to the general public who are not racing drivers. It had a little understeer then too much snap oversteer for the aspiring Sennas to handle. Hence the VX and S2 having a more understeery setup.
I see.Anyway, all that is moot because I think Tim is just trying to save a few quid after suffering a punctured front tyre.
