If you have tyres with a 97 load rating please give us a review. With the specific emphasis on the presence of tram lining/wander lust/lack of directional stability in a straight line.

In other words, does the car drive straight with them fitted...? And if you have XL (Extra Load) please mention this too.

Along with the make and model. 

Thankyou in advance.

And apologies for flooding car chat with these tyre threads, there is a reason.

Budget tyes westlake 235 45 17 97w xl. running straight with no problems so far

[tigers_gonads]

Pretty sure the 205 / 65 / 15's on the old shed was 97's and always tracked very true.
Even if you did get seasick in corners.
In fact, once you got used to the rolly polly motion, it could be thrown around with great confidence 

The 235/45/17's on the new shed dart around like a badger on heat with the slightest imperfection.
I tried dropping the pressure down from 34 psi to 32 psi and it made then much worse 
Not sure of the make but i'm pretty sure there is a mixture on there

I'm sure mine are 97's. Those funny "triangle" named rubber. Seem ok no traming but god they are noisy

[feeutfo]

Thanks guys, but next time your stood next to the car, can you varifying the exact load rating? In fact, may as well note everything while your there I guess.

Make, model, size, load rating, speed rating.

But we do need to be sure, I think. ( if that's not a contradiction )

Runway Enduro 916+ 97W XL in 225/55/16, 235/45/17 and 245/40/18

All three sizes drive true, although the 18s were a bit floaty at full load pressures, (other item notwithstanding), dropped to 34/40 psi and now much more planted

[feeutfo]

In case anyone is wondering why I'm asking. Possibly not but anyway...


Reason behind it is TramLining related, surprise surprise. The causes of TL are said to be too rigid a side wall transmitting road imperfections through the side wall. Thus pushing the steering off line via the rim, which the driver has to correct, which is highly irritating and in extreme cases threatens safety.

I'm wondering if in fact, that the opposite is true. That if the sidewall is too soft, the tread of the tyre can be pulled out of line, where as a stiffer sidewall would keep the tread in line with the wheel and keep the car straighter, and irritating the driver less with less imperfections in direction.

There's seems to be alot of 97 load tyres that behave well with directional stability on this car.

Just a thought any way.


It could be that 97's misbehave As much as any other tyre.

I generally run XL tyres (in the past) because of towing but I've never had the geometry done on this car (it's not far out by the feel, but not perfect) so not in a position to comment.

[Field Marshal Dr. Opti]

Sorry........but my MV6 sits on 94Y.

What is the practical difference between a 94Y and a 97Y?

[feeutfo]

Not sure Opti.

Afaik the omega ideal load rating is 94/95,  but with a continually fully loaded car, it might be sensible to increase that to 97, and if towing add XL.

But it's just a number really, it's what works that counts I suppose. Ultimately that's all we can do here I suspect, and as others have said.

When I buy tyres I take very careful notice of the numbers on the end:

2.2 Saloon running:
Accelera Alpha
225/55ZR/16  99W  XL

Don`t know whether it helps in your deductions/assumptions/thoughts but tyres are 99 load index as opposed to your request for 97 but they run true with absolutely no tramling, ditchfinding, "floatiness" or wandering. All running @ 32-33 psi

Thinking about it, I found the same on my saloon with same tyres

[TheBoy]

Was tempted not to reply, as not 97, but are XL

SC5 235/40/18 95Y XL. Yes, they tramline a tad
