Wheel and Tyre Question/Information Thread

I put some big fat (at the time) 225s on the back of a RWD 76 Celica 60 series I think and only 14 or maybe 15"" wheels, 205/60 on the front.
Looked bad ass, not that I'm considering 255 or something on the back on the CJ.

Having different size tires on an old car like the Celica worked from a style POV, don't think it would this time.
Can't remember if it put the speedo out by much and this was before GPS and I have no idea what the stock wheels/tires were on that car.
 
just buy damn wheels that fit in the first place. spacers are a solid no go and waste of money unless you do slip ons properly
 
To get the look I want I'm pretty much limited to x8's which only really come in 0 - +15 offset which mean I'll need to pump guards, and get coilovers & camber. Unless I spend $1000+ on genuine rims. Don't really want camber because I can't afford to go through tyres every few months. Even the camber from going Superlow springs has worn my current tyres a *poo* load :O
 
Springs don't affect camber. You just have a crap alignment. If you want the look you have to be prepared to pay for it. I'm this case either camber arms or legit slip on spacers, both costing roughly the same amount. You don't need coilovers.
 
Low springs does increase camber Rigby. And I can see it both looking at the car and by the extreme uneven wear on the tyres.

16x7's +40 with 205 or 215's and zero camber + the thickest slip ons I can fit should sit fairly flush shouldn't it?

If so $550 for a set of rims sounds nicer than $1000+ at this stage in my life/apprenticeship.
 
Low Springs may change the camber but that is only due to limitations in the factory adjustment. My rear wheels have 1 degree of negative camber because I can't get any less out of the factory adjustment and the fronts have a very minimal amount of camber.

I've done 10000kms on these tyres and have no uneven wear. If you have severe uneven wear then your alignment is definitely out. It's also more likely that a large amount of toe is causing the uneven wear and not camber. Which is what happened to me when I didn't get an alignment after putting in low Springs.
 
Why would you buy 16x7 +40 when plenty of stuff comes in 16x7 +20-30? For that matter plenty of x8 wheels come in +20-30. Save going to the hassle of extended studs and running spacers. When i had 16x7 +30 with a 205 tyre i needed a guard roll at the rear, and to cut the tabs out and that was with decently stiff coilovers. The flusher you want to make it without coils/camber/roll/pump the more scrub you will get. You can't have a cheap cake and eat it too.
 
I'm looking at some cheap replicas for$550. I haven't come across any low offset 7's or high offset 8's in that price range. I should probably get an alignment then asap :lol: My whole tyres are *fudge*ed though, torn to shreds from driving too hard ;)

I think I'll go 7's and get some slip on spacers later if they aren't flush enough for my liking. Can't decide between 205 or 215's though??
 
Guys, for track use, what wheel/tyre size combo is best. Tyres would be 595 RS-R:
1. 205/50/15
2. 205/45/16 -- These are 83 load rated which is less than what is specified on the tyre placard. 294mm rotors fit
3. 205/40/17 -- As above. Evo brakes fit (no plans to use Evo brakes though)

My question is more specific to which would offer the best grip?
Personally I prefer 15s, but I considering the brake size limitations they pose.

none of the above. might as well use R compound tyres if you are searching for the best grip
between all 3 of your options grip difference would be negligible and down to the road surface to choose which
 
Would there be any advantage of one of those rim/tyre sizes over another?
Besides of course brake size capability that is.

Keeping in mind track use only.
 
The advantage would be price.

If you are racing then get the cheapest. Mostlikly the 15s in which case you have cheapest and lightest.

Look at YEZz mirage. Doing 1.10s at Wakefield on 276mm brakes and 15s
 
What kind of power does that Mirage have?

Ideally I would prefer 15s, however 16s have the added advantage of going 294mm if the case arises. I've heard mixed reviews on how much better the 294mm brake package is over the 276mm as well.
