I have a proposal, Ryan. Downgrade your brakes and loosen up your suspension so the alignment is off. Sound like a good idea? Tyres make a huge difference to your ability to stop and go in all weathers. My view is that if you can not afford to improve your tyres at least a bit then you are wasting money planning a body kit, unless you merely plan to show the car and not drive it.

So are you saying a set of cheap NangKangs in 245-285 (or whatever size he ends up putting on there) will have worse traction than 205/55R16 that came stock on the car?
I would like to think that even the cheap tyres sold in Australia have some sort of testing done as to their ability to provide traction in different conditions... Dont they have to get approved or something for our roads?

No, I did not make the first statement Dominik. Tyre prices rise more sharply as the tyre is sold in smaller quantities, so the taller and wider the more expensive. At the inflection point of price by size, I would prefer a slightly narrower tyre of better quality rather than a wider piece of crap.
Tyres must meet reasonable standards of construction quality to be sold and have at least a certain tread depth, look and work like a tyre, nothing more. 1970s Holden Commodores also meet minimum standards for roadworthiness and any current 4WD must able to drive around corners without falling off the road .... too often. Minimum standards offer you no reassurance.
Obviously people buy what they can afford, and your second-hand buying is a smart move. I am commenting on priorities for expenditure and I have always taken a strong view that only when I can afford to buy and later replace high quality tyres for my current rims should I look at improving any other aspect of the car at all.

Actually Ryan, I couldn't really see anywhere in Rob or Davids post where they were making you buy anything. They are just telling you what they have, what they have tried and what they would do. What you choose to do with the info/advise is all up to you. Obviously you need tyres, so go with what you can best afford. Like David said, tyres are damn important. I'd hate to see what the bodykit looked like after you couldn't pull the car up in time lol.

Fair enough. That makes sense.
Btw, the tyres i got were Goodyear Eagle GSA's. Apparently the same tyre fitted to the Ferarri F40...
I note on that tyre size sheet that 225 tyres are approved for up to 9" wide, and that 265s are approved for 10.5" so in fear of castration by Rob i will say those tyre sizes shouldnt be too expensive (for a decent set of Falkens/Kumho's for example) and still ok

I am willing to help with research on tyres within your budget, Ryan. If you have not ordered the rims then choosing the tyres and seeking a package deal may give you a better price.
I will need your preferred rim sizes, tyres sizes and budget range ("I will happily pay at least X but not more than Y") PM me if you would prefer not to publish that, or start a new thread and see what people come up with. Remember that I am researching Canberra prices and that tyre deals can vary a lot between different places.
I can not help with 2nd hand buying but Dominik and others have done it and can offer experience there. Also, I may be encountering tyres of which I do not have reasonable knowledge but I will let you know what I have left out on those grounds.

Id appreciate approximate prices... if 225s will fit a 9" and 265s will fit a 10.5" thats sounds a bit more reasonable. Ive already purchased the rims and are on their way here from japan.. I dont like the look of many tyre and wheel packages here...
Well, how about a 235 for the front, and a 265 for the rear... someone told me I need a profile of 35?

I am looking for tyres to fit 18" wheels with 9" and 10.5" rim widths at Soarer rollouts. Tell me if that is wrong.
Recommend you use 265/35 at rear and 235/40 at front. These are about the minimums to fit your rims (although a 225/40 or 225/45 should also stretch to fit).
Rob made a case for the Federal S595 above. I do not know the tyre but if it is as good as he says then it is a bargain. Mark favoured the best Falkens but you will need to price them. I have not.
Of the ones about which I know something, I suggest Kumho Ecsta 712. The Hankook K104 is at least its equal in performance at the same price, I am told by a reliable supplier, but I have no other knowledge of them. Rob commented that the Kumhos may tramline more on your offsets. Price in Canberra for these is about $1250.
You may also wish to check the American Maxxis MA-Z1. Wheels rated these over Kumho and Toyo in a wet comparison (but not in the dry) and you should save about $200 over the Kumho or Hankook.
Tyre sizes and profiles which should fit your car are these, arranged from smallest total diameter to largest: front 255 / 35 -2.8% 225 / 40 -2.4% 235 / 40 -1.2% 245 / 40 0% 255 / 40 +1.2% 235 / 45 +2.1% 265 / 40 +2.4%
So, if you had more money to spend you might want to match up 275 or 285 at rear with 245 front but, in keeping with my general position, I would want to able to afford a set of Dunlop S9090, Goodyear F1 or similar high grade tyre as described by Rob before I would push up the size. They will do more for handling and stability than a slight size increase will do for grip.

According to Top Gear, as reported from conversation with a Ferrari test driver, if your Ferrari comes with Bridgestones then before leaving the showroom you should tell them to remove the Bridgestones and fit the above Pirellis or Michelin Pilot Sport II. That way, you go faster ... as if that were your major problem at the time.

Simon, I had PZeros and they were very good. Now I have the Falkens. Cheaper and better when new (surprised me!). I'm yet to find out how they will age.
I've been running Falkens for the past 6-7 years, and still none of them have surprised me. I've tried 326, 451 and 512 models. Best would be the 512s but still not a stunner.

FK451's. Maybe it is a combination of them being new and the rears a sh1tload wider, LSD and 50mm offset wheels but they do seem rather good especially in rain. Too many things different to be sure. I certainly expected a bit of tail-out action in the wet with wide rubber but there's none of that. The LSD would help there as it has to spin both now and simply can't do it. Next time I'll order the PZeros in (was going to take too long to get them).

Chris Ryan, on your 8" rim you could run to a 265 but will experience a bit of sidewall flex due to the bagging of pulling the bead into the rim which is considerably narrower than the actual tire.
Dom's definitely on the way to becoming a eunuch!
Not too many tire places out there that will actually stretch a tire in Oz. They just don't like it as it falls outside of the suppliers warranties.
Lets 'presume' that a 275 has a fitment of 9" to 11" rim. The supplier will rate that tires load carrying capacity (Ie:93w) on the 'optimum' rim fitment, which in the case above would be a 10" rim.
Now if you change from optimum, and certainly outside of the recommended mounting width for that particular tire, then you will have a serious effect on the weight / speed rating of the tire.
This is due to the varying strain placed on the sidewall from either stretching it onto too wide a rim, or bagging it from un undersize rim. The load rating is primarily derived from the sidewall construction when running the recommended pressures on the recommended rim fitment.
The link above to rim fitment is too generalised for me. I prefer to actually go with the manufacturers recommended rim widths for the specific tyre. This ensures correct fitment, load rating, speed rating and ensures warranty coverage.
I won't run a Falken tyre because the importers (Transport Tyre Services in Moorabbin Victoria) are a pack of useless, ignorant scamming motherfarqers who will not warrant nor stand behind their product in matters of failure.
They can stick their Falkens in a place where their mother's won't kiss them! This matter relates to a Falken 326. I have no experience with newer Falken models and wouldn't give the aforementioned asswipes a cent of my cash anyway.

I can relate to that So far I have no reason to complain. In fact i had a bit of an altercation with a tip truck overloaded with rubble the other day. Most of said overload was dumped on my car costing me a windscreen and one of the new Falkens. The guys who supplied the tyres (Quick Fit, Queanbeyan) got me a new tyre at their cost and fitted and balanced it for free as well as touching up damage to the rim free of charge. Couldn't be happier with them, still pissed at the truckie!!! Amazingly there was no damage to the paint on the car, a tribute to Toyota for sure.

I have falken azenis rt215 (semi slicks) on my soarer, but yet to give it a spin, however I had the same tyres on my last car a 200sx and it handled and gripped off the line awesomely. Also ran a very nice 60ft time at the old eastern creek with them tyres. They cost 270 each for 255/40/17 and 200 for 235/45/17 to suit 17" supra rims. You can't get them in a 265 unfortunately.
They have replacements now for the RT215 called RT615 now.
