Sorry - Ignore/delete this thread. They're not XL-rated in the right size. Duh.

I've currently got Phi's on the front and some horrible noisy Forceums on the rear, but all four are approaching the wear bumps.

I'm very very happy with the Phi's and was going to order 4 new ones, but they now have euro ratings and they are E-rated for efficiency, which is a bit low. It's not as bad as it sounds - if you look around they all have low ratings as the ratings are meant to be tough. But the Altenzo were a similar price but C-rated. But then I realised they're not available in 225 XL. Bum.

So I had another shop around and the Phi's still look like bargains, even with an E rating. I will try and find out whether it's a false saving though - it may be cheaper to get a more expensive C rated tyre and save on fuel. I've only read some pretty ambiguous words about what the ratings amount to in real terms, will read more about it.

But they are less than half the price of most others, and they grip and wear well. I'll probably stick with what I know and get 4 of them. Even a posh tyre could turn out to be noisy and/or wear quickly.

What the ratings mean

The difference between an A rating and a G rating could mean a reduction in fuel consumption of up to 7.5%. To put this in real terms, choosing A-rated tires instead of G-rated tyres could save you more than 6 litres of fuel every 1000 kilometres.*
At an average petrol price of £1.50 per litre, that adds up to cost savings of more than £300 over the life of the tyres.*

*Based on an average consumption of 8 litres/100km, a fuel price of £1.50/litre, and an average tyre mileage of 35,000 km

Has petrol ever been £1.50? So the difference between A and G is £300 using their dodgy price, at 35 mpg. On that basis, the difference between C and E must be less than £100. So I'll stick to the cheapy Accelera Phi's, thank you Goodyear!

the euro ratins are self regulated by the manafacturer i was told.

if they have a low engergy rating it means they are gripping more

camskill are doing a good price on uniroyal rain 2 atm

Yeah, these ratings are telling you about a small part of their characteristics. We'll probably end up with crap dry grip and handling as they try and get the best ratings now.

Those Uniroyals are £112 each - you could get 2 Acceleras for that!

the unis have the V tread pattern though, that is very good at removing water from under the tyre.
I'm not ready to buy yet, I'm waiting for a cheque to come from when that woman went into the back of me

I used to have some Goodyear Eagle F1's on another car years ago with a V tread and they were superb - quiet and handled great. Very soft though, so wore quickly.

My Forceums on the back have a V tread, but the tread is unusually wide. I think this is what makes them hum a bit. I'll be glad to get rid of them.

You can't use a directional tread on a spare. If you have an 18" spare that is - I got a scratched Astra wheel on ebay years ago that has identical specs to the Croma ones. It just fits into the well under the boot, but I did have to pack the floor up about an inch. I've been very glad to not have the pram wheel on the 2 or 3 times I have needed it though. It also seems to handle better with the extra bit of weight low down at the back.

I did read loads of reviews and forums before I got the two I've got now. I could be wrong, but it seemed to me that everyone saying they weren't very good was driving a rear-wheel-drive car. I don't know why that would make a difference though - a good tyre should be good on any car. Perhaps it's just that they drive a Beemer or Merc, so by definition are brand snobs, so won't believe they could possibly be any good!

I'd say I drive sensibly but not boringly, and I'm happy that they're safe. I've toured around Scotland and Wales with them (very wet in Wales), and didn't have any nasty surprises.

I've also done 2 or 3 emergency stops too, one in pouring rain/flooding on the motorway from 70-20, stomp on, ABS all the way. The car in front was getting further away as I braked, not nearer. It was the one behind that was getting nearer.

I don't know whether you'd want them for a track day, but I'd say they're fine and am happy to get more.

Some interesting info/comparison about Continental/Accelera...

http://mobile.pistonheads.com/gassing/topic.asp?h=0&t=878322&r=23138672&hm=18653&mid=18653

Looks like a classic case of a western company thinking they're being clever by outsourcing then finding that the eastern company nicks all their knowledge and goes it alone. This is happening across all sorts of industries. I'm happy to take advantage of Continental's bad decisions though.

If any of that is true of course.
 
I previously had Accelera Phi's on the front and some Forceum ones on the back. The front ones have worn out (after loads of mileage, so no probs), but the back ones were making a humming noise like the wheel bearings were going. It was getting louder as they were wearing down.

I've just had four new Accelera Phi's fitted and have had a good drive round, including some motorway. I'm pleased to report that the noise has completely gone and they're superb. They're not silent at speed (no tyre is), but they're pretty quiet. You can easily hear the engine in 6th gear at 70mph now, whereas before you couldn't. The bit of road noise now is a normal "aaaaaaaaa" noise, not the "mmmmmm" noise I was getting with the other tyres.

I've also given it a good chucking round a wet roundabout and nothing bad happened. I'd go as far as saying I can't imagine how you could improve on them for any price, and it would be a waste of money to buy anything else - I certainly won't. £50-odd for these or £100-£200 for anything else.
 
Just get some proper Acceleras. All 100% correct spec.

It must require Y for a reason, probably related to the fact that the Croma's a big heavy lump of a car. It doesn't mean you can get a W rating just because you won't go over 168mph. Speed ratings have the wrong name and units - they're more to do with weight and power than speed.
 
They're great. I find that the huge front and rear overhangs mean you can't see the tread on the wheels anyway, if that sort of thing bothers you.

Even more so on your lowered one.
