Geoff's 250 SWB Replica Build

I do hope that's photoshopped.

If not, that twin turbine sound is Sergio Pininfarina and Enzo Ferrari spinning in their graves.

Sacrilege.

Some things are just plain tasteless. Coincidentally I found this wonderful critique of customer taste on Longstone Tyres web site earlier today -

Some people think that an e-type Jaguar looks good with a white wall tyre. They are wrong. However we can supply the 205/70SR15 Hercules white band tyre. This is a tyre fitted by a lot of car dealers because the price is low. The speed rating is not really suited to an E-type Jaguar, but we have to accept we are in business to make a living so here they are.

XJ6 Tyres
The Jaguar XJ6 was the first production car to fit the new low profile tyre technology in the size ER/70VR15 (which is the same as a 205/70VR15).

The tyre we have here is a 205/70SR15 Hercules. With a thin white band on one side. This white band can be fitted facing inboard so you can't see it and your car wouldn't be made to look vulgar by having a white band on its tyres. this 205/70SR15 Hercules tyre has a speed rating that is not really suited to an XJ6 however at present it is the lowest price tyre in that size.


Oh I do like their style. :)

Oh, it is the wheels you object to, I thought it might be the rounders or the fact it is not silver. :-)

Not really suited = actually illegal.

I was surprised when my tyre shop said that winter tyres "didn't really need" to be properly speed rated.

I bought the Falken Euro All Weather tyres specifically because they were V rated to match the 150mph E-Type wheels on the 143mph Z3 car.

Isit illegal to run tyres that are rated below the cars VMax?

My Merc is limited to 206mph which is above the current tyre rating and it passed the MOT

In the UK you can run lower rated tyres provided you don't go over the speed rating.

No, I actually really like that dark burgundy red colour.

On the tyre speed rating thing, in the UK it's perfectly legal for private car owners to fit tyres of any speed rating to any car as you can't legally drive at more than 70mph ( I can though, muhahaha. Muhahahaha!).

In Germany of course, there are stretches of autobahn where you can drive as fast as the car will go (and the traffic will allow), so it's a legal requirement to have the correct speed rating.

In Italy it doesn't matter what tyres you fit as long as they look really stylish.

In America it's important to fit the worst tyres you can find so that your family can sue the manufacturer when you crash and burn.

And if you're a car dealer with a Z3 for sale it's important you fit bald tyres and put in the ad that it's got a/c and cruise control even though it bloody hasn't...

The Motor Vehicles (Approval) Regulations 2001
Quote:
16. Tyres
6. Each wheel on each axle shall be equipped with a tyre which has a load capacity such that when the axle is loaded to its maximum permitted axle weight, the weight transmitted to the road surface by that tyre does not exceed that load capacity.

7. The speed capability of all tyres fitted shall be not less than the maximum design speed of the vehicle.

Has the law been changed since then? Or is it just for new vehicles (why)?

I would expect an insurance company to evade the claim if lower rated tyres were found to be on a crashed vehicle even if they didn't cause the event.
25 Mar 2015, 10:47pm
That's my understanding too Ian, it isn't just the outright speed capability, with that come the ability to withstand the power which is transmitted through the sidewall without rupturing the fabric.

Insurance companies tend to check out such 'trivia'. The last proposal form I had they wanted to know the make and size details of each tyre fitted to the car??? Not sure if you were supposed to contact them if you happened to have a puncture...

I doubt that's true, and you'll probably find your insurance company will do their best to wheedle out of making full payment in event of a claim.

Hmm. I need a new pair of fronts, the tyre bill may just have gone up.
26 Mar 2015, 6:56am
I'll check today and get back to you this evening. I was going on advice from a classic tyre supplier and hadn't looked it up in the legislation...

Just a thought: can you get a V rated space-saver spare?
26 Mar 2015, 7:06am
Just googled and my tyres are okay. Dunlop Sportmaxx Z rated

Z rated only actually means in excess of 149mph but tyre manufacturers have added

W if it is rated up to 168mph
y if it is up to 186mph
(y) if tested in excess of 186
And they leave is as just Z if it above that apparently

The Dunlops are what came fitted by Kleemann when it left their factory so I should be okay.

That will be helpful :smile:

Doubt it, I think mine has 'use up to 55mph' or similar moulded on the sidewall.

Direct from the horse's mouth today (a contact who's a collision investigator) -

You can be prosecuted (and under some circumstances imprisoned) for fitting tyres with a speed rating below the design speed of the vehicle.

To clarify that, the construction and use regulations are ambiguous, stating that the tyres must be suitable for the purpose to which the vehicle is being put.

The Motor Vehicles (approval) Regulations quoted by IanA above (and which I'd never heard of, so well done for finding them!) however, state that the tyres must be speed rated not below the maximum design speed of the vehicle.

Where the Courts are concerned, if two pieces of legislation seem to contradict each other, it's the one that hangs you that stands.

According to my contact, if you fit lower speed rating tyres to your car than it should have, the chances are nobody will ever notice (I don't believe it's even checked on the MOT).

But, if you are involved in a serious injury or fatal road traffic collision, your vehicle will be checked over in fine detail by a trained collision investigator, which includes checking the speed rating of the tyres fitted to the car against its design speed. If they are found to be incorrect, it is highly likely that you will be prosecuted for dangerous driving or causing death by dangerous driving, and such cases have been successfully prosecuted in the UK.

So, I would strongly recommend that you fit the correct (or higher) speed rated tyres to your car (I certainly will be) as the 'wisdom' on the net that you don't have to is wrong.

Where the Z3 donors are concerned, this means H rated tyres on 1.8, 1.9 and 2.0 models, V rated on the 2.2, 2.8 and 3.0, and W, Y or Z rated tyres on the 3.2M models.

Just a thought...going by the thread title is Geoff actually getting a car????????
26 Mar 2015, 8:18pm
That`s the plan , Geoff .

It has been a fair while but it will be worth it , thanks Geoff .

Geoff, I saw yours when I went to collect mine yesterday.
When it's built the fiddly bits will all have been worked out already so it should be a smooth build.

Mine was the first customer car that Chris had finished, and as you'd expect there were one or two small issues which will soon be sorted for future builds.

Having driven mine the 250 miles home yesterday, I'm in no doubt that it will be worth the wait.

Cheers, Bob.
