TREAD DIRECTION

Postby ColinB » Tue 29.04.2014, 20:58

A question I'm embarrassed to ask.
I just got some Toyos fitted. I took the wheels in to the garage as I don't trust them jack
up the car safely.
Which way do the tread V's point. I assumed forwards but am not sure.
That is the point of the V hits the road first.
I could see no direction on the tyre itself.

Hi Colin. I found this info for you:

My understanding is the "V" always points forward. That way the water is directed back and to the side.

Its not uncommon to find tyres which only come one way and go on 'backwards' on one side. I spent several weeks panicking about the £1k worth of winter tyres I ordered but apparently its fine. Arrow on the tyre should show direction, if no arrow, no worries (he says shivering with fright).

Lotos,
Thanks for the pictures. it is as I guessed. I shall miss doing power slides round the bends.
Jeemy,
1K?? you must be a baron!

Thanks guys

It was 2 cars' worth! Plus I really want to keep the missus and baby safe while she barrels around in her Mini.

I fitted the wheels back on and went for a spin,
Before, the handling was fairly neutral. Now when I apply lock, nothing seems to happen for a
split second and then it turns in more than I intend and I have to correct. Perhaps they require
running in.
I have Goodyear Efficient grip on the front with only 3-400 miles on them. They were fine with
the old Michelins on the back. Now the car seems a little nervous. (Me too)
I will run them for a little while and see if things improve with a few more miles.
If not I shall reverse their position. ie. front to back. and see if it improves things.
I have only done about 8 miles.
Any comments anyone?

When viewed from above, the tread's 'V' should point forwards.
What pressures are you running & what wheels do you have fitted?

I checked the tyre pressures - they were 34" psi I think perhaps 28 would be better. I can
try that tomorrow. Will report back then after test drive. My wheels are the standard OZ 15 inch.

New tyres are slippery as they still have the release agent on them that is used to get them out of the mould. Drive easy for 100 miles before you change anything.

I've done about 25 miles now and taken the pressure down from 35 to 27. It feels much more planted and responsive now.
I wait to see how they handle in the wet.
Thanks for the useful comments.

A contributor to a change in handling from your previous set up could be a weight transfer from the rears to the fronts. Worn rears being replaced with new tires would typically raise the rear about 1/4" (new tread depth of ~10/32" vs worn tread depth of ~2/32"). In addition, the last time I bought Toyos (a few years ago for a car other than my Elan) they were visibly taller than the Goodyears they replaced - when I commented on it the tire dealer confirmed that Toyos ran taller - Tire Rack mentions on their website that the actual size of tires with the same stated size varies by manufacturer. If your new Toyos are naturally taller than the Michelin's you replaced (like they were my old Goodyears) combined with the increase in new tread depth could raise the rear enough to cause a discernible change in handling from the previous set up.

Hi,
I have just fitted new plugs and leads as previously I was getting hesitation when accelerating through 90/100. This
has cured it, but now the change in handling at that speed with the new Toyos on the back is frightening.
Has anyone put Toyos on the front with something like my almost new Goodyears (300miles) on the back?
The current handling at speed is like permanent oversteer. Normal corrections to keep the car straight result
in twitches each way as I correct the oversteer.

1) You should replace all 4 tires at the same time, and certainly have the same tire on all four tires.

2) Sounds like you may have alignment issues - if the toe is out of whack that can cause oversteer issues. (From what I've heard, I'm no expert) Correct geometry is key, especially in our cars.

I would agree with this.
