HELP

I bought a 1993 MR2 tbar just last week unseen

.

The previous owner has been kind enough to offer to MOT the vehicle for me which he told me needs a new clutch and ONE tyre

.

As I never fit one tyre and always fit a matching pair I started to have a look around on the web
According to the seller the tyres on the car now are

:
195 55 r15

FRONT
225 55 R15

91V REAR and its the rear one that needs replacing

.

this information was a bit surprising as I thought the fronts should be 205 not 195 and I also thought that the profile should be 50 series and not 55 series

.

I have read various opinions on this website and others and i am now more confused than when i started out

:evil
As i see it these are my affordable options

1

buy two 225 50 15s
2

buy two allegedly standard 225 55 15s
3

buy two 225/45 15s
Q of these three options which is the best choice for grip/ handling

/comfort
Alternativly I could dig out of storage in my garage two near new Pireli Pzeroes size

225 45 17s as I have noticed

( with no little interest

) that some pundits have 17" wheels on their own cars

.

If I go down this route I would of course have to buy two new/or ebay Mag wheels

.

This of course would be offset against the two

"free" tyres

How would these changes affect life

.

.

.or indeed life expectancy if i keep

what ive got on the front

.

Any helpful advice would be much appreciated

Kind regards Brian
