(Quite Long, Dont Read if you are time poor)
Simple statement really and to be honest, I'm not sure that I really subscribed to it.
But let me tell you....I do now. (Probably)
I know this had been touched on in various threads but thought I would start a dedicated discussion.
(Mod, please tack on if another thread exists. Did a search and came up blank)
I was fairly alarmed recently at the rate my X Power is consuming its rubber.
The tyres have done 9000 miles since they were fitted and the rear tyres are already down to 4mm.
I usually change at 3mm so reckon I have at best, 4 months and 3 to 4000 miles remaining.
To give me the best chance of achieving this target, I have put the rear tyres on the front of the car.
The fronts were on 6mm. (Now on the rear)
I do this with all my cars as I prefer to change an entire set of 4 tyres at the same time.
When I come to change them, I expect them to all be on 2 to 3mm.
If I get 13000 miles out of the set I will be really pleased.#*
I know its not a huge amount of miles, and some folk will be able to get 20 to 25 000 miles from their tyres, but for a performance car (and a heavy one at that)
I don't think that's too bad.
Anyway my point.....
I do now definitely think that Regen does indeed accelerate tyre wear, especially on level 3, which I am on permanently.
I suppose it makes perfect sense when you think about it.
(Well it does if you are using Regen on level 3)
Just one example of this is, coming up to a roundabout from a NSL road, and leaving it really late to come off the throttle or disconnecting ACC.
This will give an excellent braking effect without touching the brakes, and you can (usually) just smoothly pick up the throttle and carry on without bothering the brake pedal at all.
The drag created in the Regen phase, is obviously coming from the tyres contact with the tarmac, which in turn will increase tyre wear.
It just has too.
I wasn't really convinced about arguments that have been had on here, saying just that, but after inspecting my rubber this past week, and considering how I drive the car, then this really must be true.
Yes, I occasionally drive her hard.
Yes, I will give her the berries in the twistys.
And Yes, she is putting approximately 475kg into each contact patch.
But I reckon 97% of my miles are sensible and mechanically sympathetic. (Stop laughing Tony)
So on reflection, tyres cost more than brake pads, so I really should use less Regen and more brakes.
If only MG brake pads were a sensible price, which at the moment they are not,
then I would probably opt for Regen 1 all the time.
EDIT.
Yes, of course the action of braking itself will cause wear on the tyres, but surely to a lesser extent than the Regen?
What say ye?
