Matt _Aero top_ Posted August 22, 2007 Share Posted August 22, 2007 Why does someone here not get the 40mm and 35mm depth thing? i havent read the whole thread, 40mm up front and 35mm rear seems to be popular too, when i had 18s i had 40mm all round with 235 front and 265 rear..i also had Dunlop 9000 which i found v good Did it look like a wedge of cheese driving down the road ...... lol . No seriously dude thats not how it should be done . Quote Link to comment Share on other sites More sharing options...
SupraGirlie Posted August 22, 2007 Author Share Posted August 22, 2007 Supra girlie .......... listen to the majority of people and go for the 235/40/18 up front and 265/35/18 at the back . The choice of tyre is totally upto you and your budget . Lol yes I did decide on those tyres already My budget isn't huge due to how much the wheels are costing, but I realise they are very important and can make all the difference. The places I have rung are trying to give me Kumho's or something or Toyos. These are budget ones I think, but then if I ask for an upgrade the price jumps by hundreds!

Matt _Aero top_ Posted August 22, 2007 Share Posted August 22, 2007 i think kumho or toyo's are both agood alrounder Quote Link to comment Share on other sites More sharing options...
SupraGirlie Posted August 22, 2007 Author Share Posted August 22, 2007 Oh right ok, I was told rainsports or something was good, they also offer Avon for the same price I think and Toyo T1 R's were like 100 extra. Quote Link to comment Share on other sites More sharing options...
dangerous brain Posted August 22, 2007 Share Posted August 22, 2007 Because the profile is not in mm mate its in a percentage of the width of a tyre. A 235 40 18 is not the same depth of tyre wall as a 285 40 18 mate its actually deeper which is why the wider the tyre you have to keep the rolling radius of the whole thing the same you need a lower profile.

dangerous brain Posted August 22, 2007 Share Posted August 22, 2007 yeah i know this So whats with this bit then? Why does someone here not get the 40mm and 35mm depth thing? i havent read the whole thread, 40mm up front and 35mm rear seems to be popular too, when i had 18s i had 40mm all round with 235 front and 265 rear..i also had Dunlop 9000 which i found v good I know about tyres and your 40 and 35 mm thing is confusing me rofl Quote Link to comment Share on other sites More sharing options...
Tones Posted August 22, 2007 Share Posted August 22, 2007 So whats with this bit then? I know about tyres and your 40 and 35 mm thing is confusing me rofl i always thought that 235/40/18 for example, the 40 refers to the depth of the profile, ie: 40mm? no???

dangerous brain Posted August 22, 2007 Share Posted August 22, 2007 Nope. re-read my extra confusing post above or just click the link to the tyre size calculator for a more professional explanation Quote Link to comment Share on other sites More sharing options...
hoff Posted August 23, 2007 Share Posted August 23, 2007 You will notice usually that as the wheel gets bigger the profile will increase systematically to match. I run 265/30/19 on my rears but if 18s it would be 265/35/18 for example. I think:rolleyes: Quote Link to comment Share on other sites More sharing options...
tango Posted April 4, 2008 Share Posted April 4, 2008 Hi guys, I going to get the stock 17" wheels on my supra 8" front 9.5" rear, can anyone confirm that 245/40/17 and 275/40/17 will be good setup on it, or any sugestion? tyres Im think of are falken 452. thanks Quote Link to comment Share on other sites More sharing options...
hoff Posted April 4, 2008 Share Posted April 4, 2008 235/45/17 up front and 255/40/17 rears I believe are the sizes that toyota put on the car. Have a search on here though, there should be some info to back this up somewhere:) Quote Link to comment Share on other sites More sharing options...
tango Posted April 4, 2008 Share Posted April 4, 2008 Yes I know these are the stock size, I just want to go a bit wider, will these 245/40/17 front anf 275/40/17 fit? cheers Quote Link to comment Share on other sites More sharing options...

No 40% of the overall width of the tyre...hence having a lower profile on the rear if wider tyres are fitted to keep the overall rolling radius the same.

bodilx6 Posted April 4, 2008 Share Posted April 4, 2008 ok, i apoligize in advance if this is not usefull, since I didn't bother to read all the posts in this tread. But try to google "tire size calculator" and you will get a hit that includes something about miate. Thats a really good calculator in which you can inter stock sizes (find on mkiv.com) and your wanted tyre. You can then find what ever you want withing what ever magin you find acceptable (it will show you sizes, diameters, rolling cirum. and so). Then its just to order..
