Can you recommend tyre sizes?

[ChrisCurr]

I've just bought a set of 16" x 7" wheels without tyres. What tyre size would you recommend?

205/40
195/45
195/40

Any advise appreciated.

205/45s

Standard 182 wheels are 7" wide IIRC 195s will be cheaper though

Have a look at the different costs on an online tyre place, then come back to us lol

 

[ChrisCurr]

True, I realise the price will be different.

Don't you think the 195/40's would make the handling best?

 

[White16valver]

I imagine they would make the handling less 'flat-footed' than the wider sizes because they'd tramline less IMO.

keep in mind a change in tyres size makes your speedo incorrect, fun and games when going through speed cameras or faced with a copper with a gun aimed at you

A smaller profile like a 40 as opposed to a 45 would mean the wheel rotating more and making the speedo over read a bit so you would be under the speed indicated by the speedo.

It's the other way around.

It's the other way around.

What do you mean?
I just found this rather helpful thingy

I've just got 15's on my 182 and they have 195/45's where they should have 195/50's. Even with the smaller wheels and lower profile my speedo will only be around 5% off so @60mph I will actually only be doing 56.5mph (if speedo is accurate in the first place)

My car had 14" wheels on it, I now have 15" wheels on. (think they were 55 tyres before and now their 50)
And when I go past one of them signs that tell you what speed you doing they tell me I'm doing 4-5mph less than what the speedo reads.
:rasp:



edit: If they were 60's that were on the 14's your theory would be correct! so they may have been! :rasp:

195/45

 

[ben81]

205/45s

I'd stick to 205/45's too.
My 195/45/15's do look decidedly weedy in comparison to stock!

99% of Renault speedos over read from the factory anyway, our Kangoo at work was way out lol
