Good idea Jaster.
I have 185/60R14 tyres on my Pollux rims on both cars.
Goodyear Eco Contact Premium
I'm have four Goodyear Eco Contact Premium on the E-reg car. It was previously running cheap nasties on the rear which had age hardened but I thought I'd try and stretch them until MOT time. I spun it on a roundabout a few years ago... I changed them immediately after that little incident! They seem to be good tyres. The 480 does get a good thrash quite often and I now have no complaints tyre wise. I think these were about £50/tyre, unfitted.
Avon ZT-5
D-reg car is about to run Avon ZT-5. I haven't driven it yet on these but I put four of these on my wife's Mini Cooper R52 and they quietened it down a fair bit and it grips very well. I'll report back once I've got an MOT on the D-reg car. The price was very very good at about £35/tyre, unfitted.
Michelin
After running a fair few hydraulic Citroens in the past, I have a soft spot for Michelin. The C6 has Michelin Primacy 3. I really wanted to put their Cross Climate's on the D-reg but with all the other expense getting it on the road, it seemed a bit extravagant.
There's lots of whinging about perishing sidewalls on Michelin's. Do remember that the rubber isn't doing a great deal structurally, the tyre case is what holds the tyre together. Therefore, you can live with some perishing due to ozone reacting with the sidewalls. Of course the tyre monkeys will do their best to persuade you otherwise to sell you a new tyre early.
Winter Tyres
Regarding winter tyres, I had some on my Turbo when we had that insane winter a few years ago. They were brilliant for those few months when they were needed in the UK and I went right up north with them. I found that using the chart on this site, I could alter the tyre size and still by compliant with the Volvo manuals and get slightly skinnier tyres on Atlas rims. I went from the usual 185/60R14 to 175/65R14 for the winters as I figured skinnier was better and they were significantly cheaper.
