Tyre load rating, can someone please have a look?

[team_v]

Does anyone know anyone who's actually changed their factory wheels on an R36? (to anything bigger than 18's)

18 inch rims on the R36 are definitely big enough! You wouldn't want any less profile tyres than the stock 18's come with, unless you want to compromise handling. Lower profile = worse handling (unless you want lack of grip). If you want better handling, simply pump up the tyres to their higher load setting and spend the dollars on suspension modifications.

Unless all you want to go for is the looks associated with a bigger rim of course, because then handling doesn't matter. But even then, the 18's on the whole R range, R32, R36 and R50 all suit the car perfectly. If you don't like them or don't like the look, then don't buy the car to start with.

Thanks for your opinion Rocket, I know you don't like changing anything from the factory look and that's cool, I do.
I won't start a debate over the handling issue, I don't agree with you but again, you're entitled to your opinion.
As to me not buying a car due to it's wheels? your comment is not warranted nor appreciated and why I bought the car is frankly nothing to do with you so you shouldn't make such negative comments when they're uncalled for.I don't dictate to you what you should do, don't presume to have the right to tell me what I should.

It's not my opinion that low profile tyres handle worse than standard profile. It's proven at any race track. Do some times with normal profile tyres on standard rims, then change nothing execpty larger diameter rims and lower profile tyres and you will NOT be able to match the times. They simply slide across the surface too much rather than gripping up.

Now I'm happy to prove exactly the same thing with the R36 if someone has some larger rims with lower profile tyres they're happy to use to further prove this FACT about larger rims with lower profile tyres doing nothing but changing the look of the car.

As for my other comments, they aren't un-called for. They're my opinion, which I'm entitled to regardless of whether or not you appreciate my opinion or not.

sure its your opinion and your entitled to it...dare i say it, you probably have some valuable information to share....its just that your bone headed, black and white, aggressive tone is wearing a bit thin....but hey, its the internet, i should probably just get over it...

[Rocket36]

Yes I'm black and white....

But I don't think I'm bone headed or aggressive. Give some specific examples so I can make any necessary adjustments. The LAST thing I want to do is piss people off.

Think you are talking absolutes when there is really more to the tyre profile / handling limit ratio.
TGA is not all that good a ref in my opinion although their particular segment had some merit.
The ratio of actual side wall to width on the supercharged crumpledore would give almost no flex - the standard 20" on the r8 is not much better.
Think the diff on R36 18" to 19" is not as extreme as the TGA example.
Also think tyre choice is important here.
I have 19" on my Evo X MR and it out handles the standard 18" wheels it came with all day every day - but mainly due to tyre choice.

I have noticed you always like to start a debate (to a point where it sometimes become quite negative) about anything that involves non standardising the car. Its appears like you are trying to defend youself or your car because you have gone with the standard. Anyway, just an observation but please note I am not being critical here. Only because you asked for example but you probably want more specific example, then read the old treads that you have replied to, some which have already been deleted.

A mate of mine track races his R32 Golf and he removes his 18's and puts on 17's as they handle better.

Rocket, as you make this statement and seem genuinely interested in contributing, please take this comment in the spirit it is intended, as there are increasing comments about your opinion of your own opinion.

You add some valuable information in posts, but come over as "I'm always right".

Yes you are entitled to your opinion, but when you come over as the bloke in the room that knows everything about everything, particularly when you disagree with others who have also posted, people do get fed up with it.

Your posts in the audio upgrade threads were completely unnecessary and pissed a lot of people off. Including me as the OP of that thread.

A little humility about your opinion and the value thereof would go a long way to helping others see the value in your comments.

To the OP - my apologies for taking this off-topic.

Back on track, why is it VW's fault that Qld transport makes rules that make it difficult to put 19" wheels on one of their models?

I doubt that VW Germany takes input from any authority that believes driver training contributes to more accidents.......when deciding what wheel/tyre size combination is used on a particular model.

The motoring press is littered with test reports on VW models where 18" wheels are an option and 17" are standard, to the effect that "the ride is worse and more jiggly. The smaller wheel option is preferable in all situations."

I think the OP owes VW an apology too.

Yup! Most race cars run higher profile tyres than their street going cousins. And if you look at the most advanced race cars in the world, in Formula 1, you'll see they run very high profile tyres.

[Steve]

Perhaps I should find a way to have my R36 happily shod in the spare Goodyear Eagle F1 235/60/18's that I have

Not sure the Q7 will like that very much, though

Is it because they handle better or because they are lighter and therefore the car accelerates quicker and the suspension is working better?

[Lance B]

Is it because they handle better or because they are lighter and therefore the car accelerates quicker and the suspension is working better?

No, it's apparently because the side walls are stiffer on the 17's.

I remember hearing an interview with a quite high up company exec of a Japanese tyre company (can't remember which one) who was involved with motor sport, and he stated that around the 45/50 series profile was about the best compromise due to the fact that lower than 45/50 and the sidewalls needed to be too soft in order to allow reasonable ride comfort which would therefore lose much of any benefit in the lower profile. Any higher than 45/50 and they would flex too much due to their higher profile.

Under 40 and over 60 was much worse because the compromise was too great.

So, 45/50 was about the best compromise according to him.

[KWICKS]

No apology necessary,

I really appreciate the suggestions (and believe me, I've done the research)

All of the tyres mentioned take me outside the legal limit in Qld which is no more than +15mm.

To obtain the closest rolling dia it has to be a 235/35/19 95 (or above) a 40 profile puts me over or bigger width doesn't work out either due to the oddball load rated tyre VW chose e.g 255/30/19 is 16mm (1mm above legal and therefore illegal)

No manufacturer that anyone is aware of has a 19" with a equal to or better than 95Y rating / correct rolling dia combo and the vehicle was only adr'd with the 18's on it in mind, no upgrades (not even from VW, I asked - which is stupid as it defeats the purpose of them wanting to close out the possibility of aftermarket upgrades)

It appears my only option is to go a 20" rim with a 245/30ZR20 95Y to comply (9.8mm extra dia and correct complianced load rating)

What is the exact circumference you need? There would seem to be a large number of size combinations with suitable load ratings in a Yokohama Advan Sport On this page click the tyre sizing chart icon

I can see 255/35 R19 with a 96Y rating, 245/40 R19 with a 98Y rating, I don't think I mentioned these sizes before?
