If a car's alignment is correctly set up I fail to see the reason to correct tyre wear
Car owners in Milton Keynes regularly wear their front left far quicker than their other tyres, due to all the roundabouts. You can either more regularly replace the front left singly as required or you can balance the wear and then replace in pairs which often attracts a discount.It's referred to on the interweb (usually by tyre vendors) as "the Milton Keynes effect" but I've never seen any definitive data supporting the claim. And as an MK resident for 12 years I can't say I've noticed uneven tyre wear on any of my vehicles. Although perhaps that means I'm just not trying hard enough.

Possibly. 
I'm going to lay my cards on the table here. I may be guilty of perpetuating an Urban Myth because a) it was something my dad always used to claim (and I confess I have never fact-checked), and b) he used to claim he wore the front left on his Lotus Esprit in the 80's due to right bends being more sighted and also due to the fact he liked to "have fun" on roundabouts, and c) my own on-track experiences on clockwise circuits that I have mentioned in the thread already.
So if I have been guilty of talking b
ks then I apologise. My on-track experience stands though, but this is of course nothing to do with road driving.

The urban myth is that cars driven in Milton Keynes wear the edge of the front right tyre more than others due to the roundabouts - the biggest load on the tyres being the braking in to the roundabout with the initial turn to the left, loading up the front right tyre the most.

I drove a nightshift taxi for several years as a student and despite the cars (A6 3.0Tdi and then an E350cdi) being 4 and then RWD it was always the edge of the front left tyre that wore out first.It's referred to on the interweb (usually by tyre vendors) as "the Milton Keynes effect" but I've never seen any definitive data supporting the claim.

The miles were mostly done in town (Aberdeen) and driven how you'd expect a 19yo to drive a 3.0Tdi at 3am so maybe not entirely representative! The rear tyres on the A6 lasted ages while the Merc wore them out more evenly.
I remember the stock car saloons had outrageous front camber
lean to facilitate spectacular drifting round the corners
on anti-clockwise oval circuits, this was 20-30
years ago when RWD Cortinas, Granadas, Scorpios were the preferred platforms
Wonder what they use now, can drifting be done with a Mondeo, Astra ?

It has been researched by the Uppsala University of the Bleeding
Obvious that front tyres will spend 99.78% of their time in the
straight ahead position under no abnormal loading, [maybe a bit less if you live around MK].
So during it's life going around an average number of roundabouts, even driving like Bo Duke, must have a negligible if nil effect on excess wear.
Surely most of the wear comes from the abnormal load bit though. Cruising along a straight road without putting much power through the wheels isn't going to cause anywhere near as much wear to the tyres as accelerating, braking and cornering will. So that 99.78% of the time cruising along straights might only be contributing to 10% of the tyre wear, meaning increasing the number of corners will increase wear by more than the average wear per mile. eg a track day is going to cause way more tyre wear than the drive to the track on public roads.Obvious that front tyres will spend 99.78% of their time in the

They don't do that so they don't have to change packaging as prices change. Obviously. the actual price on the packaging in £ and p comes

I'm still trying to work out how you make a decision to add a carriage return to a message. Just for the whimsical randomness?

The barcode gives the item ID to the reader, the database matches that ID to a price. Big difference. Plus the manufacturer doesn't set the price, different shops will sell the same item at different prices.the actual price on the packaging in £ and p comes

Most interesting.I notice that store branches will sell the same item
at a different price, geographical or postcode pricing I think.
Whenever I go to London by train, I tap in and out using my Debit Card. I noticed this week that on the day of travel, 10p is taken from my account with the full fare taken the following day. a) why is this? b) what's stopping me clearing out the account and having a day of travel in London for 10p?
