Tyre advice please

[MrSix]

Once this slush goes I'll be fitting my new wheels to the car, but before that I need to get a new set of tyres.

Now the standard tyre size is 195/55/15 front and 225/50/15 rear.

The new wheels are 7.5j 17" and the tyres that are currently on are 205/40/17 front and 235/40/17 rear.

What would be the ideal tyre size to run in order to keep the speedo calibration as near as possible to standard?

Also anbody tried Falken FK452? I've been recommended them by a few people and they seem well priced.

 

[MrSix]

Thanks for those links guys...

My speedo over-reads by a few mph anyway so can potentially get away with a bigger % difference than I originally though.

 

[MrSix]

Looks like I'll be going for 205/40/17 front and 235/40/17 rear...although potentially 215 fronts may be a better option provided they'll fit without rubbing on full lock?

 

[MrSix]

The wheels are 7.5j front and rear - not sure on the offsets actually, it'll be on the back of the wheels somewhere no doubt.

 

[MrSix]

Thanks for that cee, I'll go take a look when I can brave the cold and report back with the offset!

 

[MrSix]

You need to get Ultra Super Snow Tyres now. It's the law on the internet. Infact buy a 4x4!

Don't be stupid, I don't need a 4x4.
How much are snow tyres though?

 

[MrSix]

Find out your offsets and go 215/235. I got 452's on my MR2 and they are a very good tyre.

I had a 235 on the front of mine with no rubbing but it was very close and a et32 offset. a 215 should go on without any troubles.

Okay the offset is the same for both wheels as they aren't staggered, 45.
Using the mr2 wheel calculator it's saying:

MR2 (mkii) Flushness:
Your proposed front wheel will be 16 mm tucked in from flush (flush offset: 29).
Your proposed front is 2 mm from possibly touching the front suspension.
Your proposed rear wheel will be 28.7 mm tucked in from flush (flush offset: 16.3).

Wheel Comparison:
Your proposed front wheel will stick out 19.05 mm farther than your old wheel.
Your proposed rear wheel will stick out 6.35 mm farther than your old wheel.

I'm thinking I'll probably need to run 10 or 15mm spacers for the rear wheels then, as the fronts will be sticking out more than the rears?

 

[MrSix]

Offsets are very high mate.

Id try a 10mm spacer on the front and a 20mm spacer on the back. that will be offset et35 on the front and et25 on the rear. You wanna becareul the fronts don't over stagger the rear, even then the fronts stick out more that the rears.




Also i think decent spacers that wide are not cheap at all.

I run at the moment a 16" wheel at the front with a et32 and 225/45 tyre and a rear 17" wheel with a et35 and a 255/40 tyre and thats pretty much bang on

These are my flush measurments


To be honest mate, its not gonna look that good with the wheels sitting so for into the arch well.

Hmm...what a bummer - maybe I should cut my losses and stick with the standard wheels. I'll be paying the best part of £500 to refurb and re-shoe these wheels...

 

[MrSix]

i'd sell them, then find a set of staggered wheels with much lower offsets

Just need to find a buyer willing to refurb them, they're in need of it.
Does anybody else know what cars have the same PCD as a mk2 MR2? Perhaps they would suit a different car.

 

[MrSix]

Unfortunately they don't make them for the stock MR2 wheels (they're like bloody cubes - 225/50/15). Will probably go for some Proxies.

 

[MrSix]

Cool - I'm regretting spraying one of them silver now though to see what it would look like lol.

 

[MrSix]

Looking for tyres for the MR2 stock wheels now - can anybody see any problem with fitting a 50 profile front tyre instead of a 55?
