tango Posted March 18, 2008 Share Posted March 18, 2008 Hi guys, I currently having 16" stock alloys 225/50/16 front, 255/50/16 rear, supension are stock, and want to change to 17" stock alloy, 8" front 9.5 rear, and what size of tyre widest are good for them without alter the handeling? thanks Advice needed. cheers Link to comment Share on other sites More sharing options...
jamesmark Posted March 18, 2008 Share Posted March 18, 2008 235 45 17 fronts 255 40 17 rears. There is 265 and 275 for the rears I do not think it will make that much of a difference, maybe Chris Wilson will be able to give a better answer.

tango Posted March 18, 2008 Author Share Posted March 18, 2008 is that what you guys are running on the 17"s, just the price for 255 or 265 are the same and 275 is not much more, just want to fit the biggest it will take without rubbing the arch. thanks Link to comment Share on other sites More sharing options...
jamesmark Posted March 18, 2008 Share Posted March 18, 2008 TT or N/A? If you are driving a N/A then stick with 255 as you may get drag (or whatever it is called) if you go too big on the rears. Link to comment Share on other sites More sharing options...

jamesmark Posted March 18, 2008 Share Posted March 18, 2008 I woudl go for any to be honest, I was going to go for 275 on mine but a bill came up and stuck with 255. I will be going to 275 when I need to change. Depends what you want, if you are purely interested in handling then stick with stock sizes, if you can compromise it slightly go for larger.

robin Posted March 18, 2008 Share Posted March 18, 2008 I don’t understand why people would go for oversize tires. Is it simply to have the wide look? Personally I think that anything which is likely to compromise handling and maybe even push the Speedo out a bit is a bad thing; especially bad if it costs more.

tango Posted March 18, 2008 Author Share Posted March 18, 2008 is it not the bigger the tyre the more contact area you get, better grip....... i know also depens on what make of tyre as well, also looks good. Link to comment Share on other sites More sharing options...

Personally I think that anything which is likely to compromise handling and maybe even push the Speedo out a bit is a bad thing; especially bad if it costs more. The stock handling setup could be comprimised by a pothole in one of our sh*tty roads, people generally arent that anal about the stock handling setup that they stick to exact stock tyre sizes, the tyres that the Supra came with probably arent even available anymore. I know when I went from a 265 to a 285 on the rear my grip increased in the dry but got less in the wet, I cant even imagine going back to a 255 now. People adapt to their needs, stock isnt always best.... Link to comment Share on other sites More sharing options...
tango Posted March 18, 2008 Author Share Posted March 18, 2008 agreed with you, our road are crap......... 285 is massive, but less grip on wet, tyre patten perhape........... what about these lambo with 345 tyres Link to comment Share on other sites More sharing options...
bolarbag Posted March 18, 2008 Share Posted March 18, 2008 I have a 9.5inch wide wheel so the max I could go was around 285, the less grip in the wet (Only noticed it when doing any spirited driving) was probably due to aquaplaining. Lambos and any car that come with ridiculously wide wheels stock will have had the geometery developed with them sizes in mind, its not as simple as just wider arches or crazy offsets to suit.... It is if your only interested in looks though which generally a lot folk are. Link to comment Share on other sites More sharing options...
robin Posted March 18, 2008 Share Posted March 18, 2008 Stock tire sizes are available; I have no problem in getting them. A wider tire can be a nightmare in the wet as it has to displace a lot more water. I think wider tires should last longer over thinner ones as there is more rubber to wear but I don’t think there is any difference in overall traction as even if the contact area is larger the force per cm^2 will be lower so overall grip will be roughly the same. It's always a hard thing to judge as often one is comparing brand new tires against old worn ones making the new ones nearly always the winner. If you get really bored one day try putting two space saver tires on and I think you would be surprised by just how grippy they are. Just don’t expect them to last very long at all.

Thats a pretty fair point, I once did 130leptons with a spacesaver on and my normal wheel on the otherside (Old school friend appeared didnt want to dissapoint) before thinking wtf am I doing!! Needless to say there was surprisingly a lot of grip but anything in the lower rev range the car was kicking out all over the place, but not exactly a fair comparison a 135 to 285;) I must add...never to be tried again!
