Hey all

I have a set of Advan Racing RG wheels on the car. The rear is running 265/50/R17 on it.

Now, the current Falken tyres are rat house, so I went looking at the tyre shops for new tyres (Just for prices atm) and I can't manage to get any.

Can anyone recommend somewhere in Sydney to buy them from (I'm even thinking of putting Semi slicks on it for track use)

I'm currently in wollongong.

Thanks

Sam, can you explain why they are wrong?

I don't understand how a profile can be "wrong" or do you mean wrong for keeping the speedo accurate?

As so far, I've checked it against a mates car, with basically stock tyres, and both speedos read identical...

Will the drop in size be that dramatic on my speedo reading also?

i'm not sure why, but the wider you go the lower the profile. that's how it usually works.

i have 265/35/18's on the rear, they are impossible to find in 40 series. but my front 235/40/18 are easy to get.

maybe someone can shed some more light.

You have a R33 GTS-T. That would mean the stock tyre size is 205/55/16 right?

I have plugged in a few details into a calucator that is located here: http://www.1010tires.com/TireSizeCalculator.asp

Stock Tire - 205/55R16

Rim Width Range: 5.5 - 7.5 in

Overall Diameter: 24.87 in 631.69 mm

Actual Speed: 60 mph 100 km/h

Tire 1 - 265/50R17

Rim Width Range: Unrecognized tire size.

Overall Diameter: 27.43 in 696.72 mm

Speedometer1: 54.3 mph 90.6 km/h

Speedometer Difference: 10.30% too slow[/color][/size]

Tire 2 - 255/40R17

Rim Width Range:8.5 - 10 in

Overall Diameter: 25.03 in 635.76 mm

Speedometer1: 59.6 mph 99.3 km/h

Speedometer Difference: 0.637% too slow

And 255/40 R17 are piss easy to find. You can get soft street tyres, or a more touring tyre, and most of the more "street sports" oriented companies (Toyo, Falken, etc) have a range of tyres in that size.

Since it keeps your speedo so much more accurate, I'd suggest going there instead.

that's a handy tool.

says mine is:

Stock Tire - 205/65R16

Actual Speed: 60 mph - 100 km/h

Tire 1 - 265/35R18

Speedometer1: 62.8 mph - 104. km/h

Speedometer Difference: 4.699% too fast

Diameter Difference: - Diameter Difference: 4.5%

sounds about right. thanks for that link

I will run 265 on mine as soon as it's time to replace them.

As for Falken having 255, not anymore, there largest tyre is now a 235. Don't ask me, I was only speaking to the reps.

Also, Falken = THE SHITTEST tyre ever. Absolutely, ZERO traction! Get them slightly warm, and they walk all over the road too!

Looks like you guys worked it out earlier in this thread.

265/50 is too big in diameter, the "50" is the profile of the tyre as a percentage of the width.

265/40 is much closer (very slightly larger) to stock diameter.

265/50's would look like tractor tyres?

That's true for the Ziex series, especially the 326's, but they do make some reasonable tyres.

The infamous RT215s stick like shit on carpet unless its wet and they're worn, the ST115s aren't bad as a more long-lasting street sports tyre, and I've heard that the FK451s are a good "touring" tyre.

what are you talking about mate?? Falken make probably at least 15 different types of tyre suitable for a passenger car with a 17inch rim. so i'm assuming you've tried them all? and they are all shit? or are you just talking nonsense? Sorry if it sounds harsh but it's so tiring hear people sprout rubbish.

I've tried a mere 4 different types of falkens in 17s. 1 was terrible, 1 was excellent and 2 were quite good. so you could understand why I would think it strange you think all falken tyres are crap. I also highly doubt they only make 17inch tyres up to 235 wide.

Go down to a tyre shop, and ask to have a look at the new Falken range.

As for Falken tyres being shit.

I haven't ran various ones in 17", but I've driven many a car with Falkens fitted, and not a single one will grip at all.

As for the 265/50 looking like tractors... Nope, still quite a small profile really... It's weird. I'll check them again, but I swear it said 265/50/R17

Okay, just went and washed the car, and took a VERY close note on what size they are.

Sizes:-

Front: Falken ZIEX ZE326 235/40ZR17

Rear: Falken FK451 265/40ZR17

Don't ask me what the "Z" stands for.

So as for FK451 being a good touring tyre. THEY'RE UTTER SHIT on my car.

And you can't blame my alignment either. I got it aligned 2 weeks ago incase it was out. Which it was. Badly. Stupid previous owners!

I knew you didn't have 265/50's!

But anyway.

I still can't seem to track down 265 in Wollongong, anyone know a good tyre shop in Sydney (I'm NOT talking Tempe) I'm half tempted to go and buy a set of Semis to put on the RG tyres, and buying maybe some stockies for the front and rear with just average tyres on them, for wet weather/winter days.

why not just get some 255s? 10mm difference will mean SFA. plus due to variances in different manufacturers tyres it's quite possible some 255s will have as much tread as some 265s.

      I also think it comes down to the dollars spent for quality items, there's some cheapie versions out there, which look fine, but, there are versions of much higher quality out there, but, you obviously pay more for the quality of materials used and quality control When I first got work done by Advan Performance on my old R33 the silicone joiners were cheapies and actually blew out on a joiner heading to the plenum, when I then took it to Unigroup they said that the silicone hoses they used and were junk, Unigroup replaced every hose on the engine with much higher quality items and from then I never had a issue with any hose Additional cost and quality gets you quality silicone base materials and quality reinforcement fabric stuff As for OEM rubber hoses, again, quality materials and strict quality control will give you quality hoses, but only to OEM spec, I believe using quality silicone replacements is a upgrade I  saying this I have only dealt with vehicles I own and play with

      Not gonna lie my sense of smell isn't the best. But it does look more grey to me. It doesn't smell like oil, friend says it smells like fuel.

      That's it. Too rich for me. I'm out. If it does start to sell in pieces, I'll probably register an interest in the diff & axles, gearbox & tailshaft, and maybe the brakes.

      I tried my best, well I see how it is though... It's time to be ruthless! I'll up my bid with a JVC sub and an amp to run it, 8 stainless steel drink coasters with a rubber backing, and a photo of Tom Cruise. Oh, I can increase the cash portion by 20 cents if that helps.

      Or if it's grey, is it watery? Does it do it after you've been for like an hour long drive it will still do it, or just near the start of the trip? As GTS said, does it seem like oil (blue), water (white/grey) or fuel (black)? Sometimes the colour can be hard to see clearly too for what it is, as GTS says, what's it smell like?
