Runway ENDURO 656

Don't even think about Runways on a performance car.

I had a pair on a couple of replacement rear wheels I bought for the MG TF. The tyres were almost new and still had the molding flash on them.

In dry conditions felt OK, grippy in the dry but fairly progressive; the car would make gradual transition into a drift as the back wheels lost grip. Nothing scary and easy to control and the limit was pretty high. Pretty much ideal performance for a mid engined car.

In the wet they seemed to have no grip whatsoever leading to oversteer anywhere. Not good, wet days involved a lot of tip-toeing around.

After a about a month they started cracking around the treadblocks and breaking up. They looked like they were falling apart and in a pretty dangerous condtion. I put the car in my garage removed the wheels and took them to the fitters in my other car, I wasn't going to drive on them again...

The tyre fitters who put the replacements on wondered if they'd overheated. I'm not so sure as there were no signs of blistering and the edges were well defined, the rubber on hot tyres tends to walk around a bit and this didn't appear to have happened. I don't think you can generate that much heat on the roads.

Transferred my old Toyo Proxes from my old (buckled) wheels on to the new rims and the car was back to it's grippy, predictable self.

Called into the local tyre fitters -was going to have Goodyear Eagle replacments but they didnt have them when I called but had these Runway Enduro,s - I never heard of them but they assured me they were good medium grade tyres- reasonably prices so I had a pair put on.
My first two trips out were long distance motorway ones on cold wet days -The car didnt feel comfortable and seemed slippery -then on B road roundabouts felt very slippery and uncertain - At first I put this down to the poor weather conditions- my second trip in similar conditions proved much the same- I drove more carefully than normal thinking it was the road conditions although I had never experianced such situations before (even though the previous set of Goodyears were wearing down)-- then the penny dropped that it must be the tyres- after some internet research this situation seems common to these tyres- In the dry they seem fair, but I,ve never pushed anywhere near limits-In all I,ve lost confidence in these tyres , though I,ve done about 900 miles-I,m getting rid of them in the next few days !!!!
