Getting New Tyres - Advice on Sizes - FL AD08r

[sadhvikv]

Hey,

I'm planning on getting a new set of AD08r all round. At the moment I can source the following sizes:

Year: 2004
Front: 195/50/15
Rear: 225/45/16

Will there be any problems with running that and  getting that fitted? (really inexperienced when it comes to tyres and just working off bits of information I'm getting from this forum, so any advice much appreciated)

What difference does varying from the stock sizes of 185/55/15 and 215/45/16 make?

Any help you can provide me to make sure I don't go in the wrong direction (potentially literally) with my new MR2 would be much appreciated!

Those are the sizes I'm running. Perfect setup for me.
Bearing in mind I don't drive the car to its limit for extended periods of time, and I'm on BC coilovers.

Day to day with normal roads and normal-fast speeds, the wider setup will give you more grip in the end. On dry days  s:) s:)  
Basically, 95% of the time you will only see the benefits of the wider setup... On dry days haha.. Did I mention that?

If you were to be driving at the limit (on a track) constantly, especially through hard bends, I would be tempted to run stock width. The reason being that the wider setup does make the car lose grip slightly less gracefully and make you work harder to make corrections once the tyre runs out of talent.
The stock size tyres will also respond quicker to changes in direction.

But, as I said, 95% of the time as a daily driver I would opt for the wider setup.

Having said that... I might try stock sizes  next time to compare.

Stock sizes are available for the AD08R I believe, but the sizes you mention are probably slightly cheaper. Universally the case when comparing 185/55 to 195/50.

The speedo will be out by a tiny amount, less than 2%, so 70mph on the speedo will be about 71mph, but speedometers are usually calibrated slightly down for the expected reasons.

The AD08R's are great tyres for those who don't want to commit to proper track day tyres, and I would think only pedantics would absolutely demand the stock sizes. It's literally a centimetre between them.

Stupid question alert: will these fit on stock wheels?

I am running stock sizes in AD08Rs. Theye are a stock as you can get.
