OEM Tyres?

[Hartley]

Im sorry, another tyre thread but hopefully with a bit of a difference.

A lot is said about OEM tyres being different to the rubber you can buy after market. Supposedly BMW fit inferior A41s (for example ) to your new GS. Im not sure if this is true and if it is it seems odd to me, surely a tyre manufacturer would want to show their product in its best light?

Anyway, im wondering if anyone has ever fitted the same again come change time and found the replacement significantly different to what the bike rolled out of the showroom with?

I had Anakee Adventure on mine from BMW and never again, they were so noisy compared to the Conti Trail Attack 3

Just feels better overall but I am sure its mostly down to riding style

My experience with BMW is that they fit a tyre that is at least one revision behind the current tyre. For example, my RS came with Metzeler Roadtec Z8 when the Roadtec 01 was the latest thing. My S1000XR came with Bridgestone T30 when the T31 was the latest tyre. I did not replace like with like

My previous Africa twin came with A41 tyres from new and when replaced with the same the fitter said that the tread was not quite as deep on the OEM as the new ones. Told me that Honda negotiate with tyre companies to supply cheaper versions simply to save money. I asked how he knows this and apparently he has worked with bike magazines to compare both versions. In practice I could not really tell the difference most of the time, but in torrential rain felt the replacements were more assured with better feedback, but it is possible that this was psychological as I rarely tide in such conditions. The magazine test stated the differences were significant, but cannot recall which publication this was.

That depends if they are developed for BMW or if they are an off the shelf option. Usually the tyre will have a stamp/mark on it telling you if it is an OEM tyre - not an off the shelf version.

When I purchased my Z1000sx the sales guy said get the bike run in a replace the tyres. Turns out Kawasaki fit inferior (cheap) tyres in the factory Not a good start to ownership.
Is this true of other manufacturers?

for a while some of the Japanese firms used a Dunlop Roadsmart D222. A single compound tyre that was made for OEM use only. You could not buy them retail. In Japan, Dunlop is a Sumitomo brand but owned by Goodyear in Europe. Goodyear never made the tyre at their plant in Montlucon as far as I know. My 2015 Yamaha Tracer came with them. Replaced with some nice Avon Storm 2. I think Yamaha has stopped using them as recent Tracers are coming with Michelin Road 6 or similar.

Just noticed that my 2019 1250 rallye te has Bridgestone A41’s ( fitted from new) now on 8k miles
Date on the tyres?
2012
Wtf
Not impressed

Ryan did an article on tyres

And tread depth was covered


What i can say, is the tourances fitted to the TC, have got 6k on them, and need replacing, the front showing, heavy wear

Really, I didn’t think they’d been out that long, stuff I’ve seen says 2018.

Maybe when a bike is launched, the bike manufacturer agrees with a tyre brand that they want x thousand of a model of tyre and then when a newer tyre model takes over, the contract has them stuck with the older tyre??

 

[GSite]

Sounds about right.

 

[Santa-2512]

Spot on, xx amounts of old parts have to be consumed before new parts can be introduced

hence why some bikes / cars get an option early or late depending on when the run out / run in occurs

thats why your asked for your vin when you order parts - the change is down to a particular vehicle on the production line

not like in the old days when it may have been sometime in a calendar month lol

Same on my RS. I bought it with 01se's fitted which had covered perhaps a few thousand miles. Now having covered close to 6K miles, the rear has plenty of grip left, if a little squared off and the fronts have worn a fair bit more, with perhaps 1.5mm treat depth left in the centres. I'm not heavy on the brakes and have a smooth riding style. Under braking forces, the D/C tread blocks off-centre started creating ridges where the softer compound wore unevenly due to braking and cornering forces creating small ridges towards the rear of the tread blocks, affecting turn-in stability but I rode through this wear pattern and they evened out within another 2 k miles. Could just be the 01se's as I didn't have this effect on the A41's on my GSA. Great tyres and from experience, a step up from the older Z8's which I didn't like.

My Bridgestone T31 have that same ridge at similar miles

Complete and utter bollocks, I think

So... I have an answer from a well respected source.

OEM tyres ARE different: https://twotyres.co.uk/faq/difference-between-oem-and-normal-motorcycle-tyres/

You can buy OEM tyres: https://twotyres.co.uk/product/metzeler-tourance-next-oe-fitments/
Or "proper" ones: https://twotyres.co.uk/product/metzeler-tourance-next-2/

Talking to Chris, he says to steer clear of OE tyres and fit the "proper" ones. he should know!

This article relates to tyres like the Dunlop D222 made by Sumitomo, An OEM "Roadsmart" tyre with single compound that was fitted to cheaper models by Yamaha and Kawasaki. My 2015 Tracer came with them. These were not sold in Europe as Sumitomo does not control the Dunlop brand here, it is owned by Goodyear and they do not make them.

you are missing the point made in post #1

You link to two different Metzeler Tyres. The Next 2 are at least 2 versions of development after the original Tourance. It makes sense that the newer tyre model will be an improvement.

The OP is asking if the Bridgestone A41 fitted to his bike in the factory are different to retail version of the A41 tyre in a shop. I don't think they are as BMWs sold in Europe will need to meet German TUV regs and they are very tight in terms of replacement tyres. The new bike tyres must be the same as those specified in the factory. BMW are likely to offer two options for most models. You will note your source makes a distinction in his article about bikes from the Far East and Europe.

BMW like other OEMs will fit tires they get cheap…Bridgestones or Michelins fitted on the 1250 GS for sure are not as good as in confidence inspiring on dry or wet roads as the best tires today like Conti TA 3 or Metzeler TN2 so why fit them again ? I rather pay a little more and have a better more fun to ride tire !
