Thinking Of New Tyres, Advice & Help Needed

[Nick9one1]

+1 for the Vorti's here and have yet to find anyone beat Camskill in the years I've been buying tyres online

Oh and YES I stepped up the rear profile to 35 too as per recommendations on here

Why only the rear? I was planning to up the profile on both, unless there is a good reason?

When stock the overall diameter is 25.5" at the front and 25" at the rear.

Going to 35 at the rear takes the diameter to 26"

I wondered if it would screw up the TCS if you change the ratio?

Never came across any recommendations to up the front profile and I'm sure I read about a few that had, then had problems with rubbing at the front but I guess that depends what alloys you're running, I'm on stock 326M's. Hasn't caused me any problems with the TCS and don't see why it should

[HillWalker]

Don't up the front profile leave it 35, but if you increase the width to 235 from the standard 225 you do get a slight profile increase with no problems whatsoever and a better match to the rears.

The TCS works by looking for difference in the wheel speeds. If you up the diameter of wheels on an axle, the rolling speed will be different possibly making the TCS may be more prone to activating.

So just upping the rear profile changes your front to rear sidewall height by 13mm.

Yes, not a good idea to increase the rolling radius of only one axle for reasons others have mentioned.

The car will still work and you might not notice a difference but it will have an effect on the traction and stability control of the car.

After this, Ill think I will have a serious look at the Vredstein`s, I was very much up for the Michelins, but that's what you ask advice for,, now do I up the rear profile

Vredstein? Not expensive enough.

In a very tight, very highly competitive market, let price be your guide.

You must have tried them on your E89 to offer such wisdom & insight
If i'm not mistaken you chose Pirelli for your own car why not follow your own advice

In about 2,000 miles, I shall. However, at the time, I bought the best I could afford and always will. Of all the regular expenditure on a car, tyres are the most important.

Id wager very good money you would be impressed how good Vorti tyres are & i know from my own 35i ( remapped over 35is power) they are up there with any of the big names come sun , rain or even light snow .
I covered 260 Northern France miles last February through sleet & snow , i never once felt unnerved & a major plus for me with Vreds is they perform from the outset , you don't need to put much heat through to feel confident which is the opposite of the MPSS i currently have on my ZMR , very very skittish initially on anything other than warm dry tarmac & i can't see me tackling any winter miles with them like i did with the Vreds / pic here in the Dales last January

The Ultrac Vorti is popular but there's a lot of talk about poor performance in the wet and high wear rates which makes the cheaper price tag less impressive.

The Pilot Sport 4S is still the king though. It wins nearly every test I've seen it entered into and I've had them on my car for a year and been nothing but impressed. I had Michelin Pilot Super Sport previously and I find the Pilot Sport 4S to be a little better in every way, most noticeably in the wet.

And yet the recently posted tyre reviews uk suggest otherwise, and certainly on the wear rate.
I will be giving them a try.

Real world vs simulated.

I was highly abusive to my Michelins on my old 3.0SE & yet they lasted much longer than the Conti’s on my previous new A3 which was driven sensibly

Yes, I did the online tyre calculator at the time when I was searching for answers. My priority was to protect the rears from cracking and I was concerned about the issues of front rubbing if I went up on the front profile. TC doesn't cause me any issues that I've noticed over how it was on stock tyres

If you put the sizes in willtheyfit.com it will tell you the differences in speed
