255/35/20 doesnt seem particularly bad for rubber price wise £120 seems to be decent branded rubber as i said the MP4s are £150 a corner but its a diesel taxi, it doesnt really need Super high performance rubber to trundle up and down the motorway all day a decent branded tyre will be fine.
that said an extra £30 a corner really isnt a big difference, just curious to see what the options are
as long as its not the standard Dunlops
Bugger just missed costco offering £50 cashback when you buy 2 michelins offer, would have brought the MPS4s down to £125 a corner or there abouts, no brainer at that price. cracking tyre/price
I'm going to go against the grain here and say don't go for the MPS4S if you drive a taxi. Yes they last a decent amount of time, but they come with the trade off that they are noisier, and they are harsher than the regular UHP tyres like the PC6, GY Eagle F1 A5. This is something you put up with if you enjoy a razor sharp turn in on a fast corner, excellent mid corner stability when you're pushing the car to it's limits and tyres that better resist overheating on track - but if you're not really going to benefit from that - you're just stuck with the negative points about the tyre.
From researching quite a lot in the last couple of weeks, for this type of car, I'd go for the Eagle F1 Asymmetric 5's. They are a big step up from the already excellent Asymmetric 3's and are well up there with the best, but they are also a really really competitive price.
EDIT: Scratch that, just checked and Goodyear haven't gone above 19" for the A5's tyre sizes yet
EDIT 2: It seems that that tyre size kinda sucks - apart from the Michelin PS4S, all of the other tyres are at least a generation old. There is no Premium Contact 6, no Michelin PS4, no Asymmetric 5. There is the new Pirelli but it is hugely expensive, and there is the ContiSportContact 6 but they are made of cheese and will last about 10 miles before needing to be replaced again.
Seems like the PS4S might be your best option afterall
