I have been trawling around various tyre review sites looking at possible replacements for mt tyres.
My car has 215/40/R17/87V tyres fitted.
Ideally I want to try and get a softer ride, as the roads around where I live are quiet poor, and the car feels a bit crashy over some surfaces.
I have read I can bump the tyre to a 215/45/R17, and this may improve the ride.
I would welcome any opinions on choice of tyres, and their experience of bumping up the tyre size.

Re: Tyre choice - Blue Gt 6R
Things to consider;
- The BlueGT will have quite a firm suspension set up as it’s the ‘warm’ hatch in the 6r/6c Polo range, so it might be the suspension rather than your tyres that’s the biggest contributor to what you perceive to be a slightly crashy ride.
- If your tyre pressures are too high, it’ll affect your ride comfort. Some Polos also have a ‘comfort’ tyre pressure setting (if applicable to the Blue GT, it’ll be shown on the sticker inside your fuel filler flap - you may need to cross refer with your manual to make sure which set of pressures relate to the comfort setting).
- Replacing 215/40 R17 tyres with 215/45 R17 tyres will increase the ride height of your car and reduce the gap between the tyre and wheel arch. A reduction in wheel arch gap will potentially increase the risk of tyre rub when the suspension is working hard on poor or potholed road surfaces.
- The rolling radius of your tyres will be larger, so you’ll get an inaccuracy in your speedo reading; around 2mph below the true speed at 60mph.
- Some places (e.g. Costco) actually refuse to fit different sized tyres to those that were designed to be fitted to the car.
- Fitting different sized tyres to factory spec Is likely to be considered as a modification by most insurers so you’d need to inform your insurance company.
- You might not notice any discernible difference in ride quality by changing the existing 40 section tyres with 45’s.

Thanks for the advice.
I will try dropping the pressure down to the comfort settings, see if that makes a difference.
As for new tyres, I will have to check out the reviews and balance that against the cost of 4 new tyres.

Re: Tyre choice - Blue Gt 6R
Out of interest, what tyres are you running at the moment?
I have Bridgestones on my BlueGT, and I find the ride rather crashy, even on “comfort” pressures.

It is frustrating that VW have picked an "odd" size for the tyres.
215/40/R17 doesn't seem to be a common size, and a lot of recommended tyres on the review sites won't fit the car.
I am going to try the comfort pressures, and see if the car feels any better.
It has a problem with squeaky bushes / suspension, which will hopefully be fixed next week.
After that, I will take a more serious look at swapping out the tyres.
