Good to see Another Aquamarine Pear coloured SW20 and even better a lady driving it. this colour is at its best in summer so make the most out of it, come winter and overcast skies and the colour is not so great looking but im sure you will have lots of fun with it, please do be carefull in the wet weather with these cars they are not the same as others and will quickly bite you if your not carefull.
ideally the wheels should have been wider in the rear than the fronts but dont worry many people have run the same width all around before and have been ok with it. just dont drive like a crazy person lol
 
cheers

...The problem with having the same offsets and width front and rear on an MR2 is that the front wheel track will be wider then the rear.

Just to clarify, wheel width does not affect vehicle track, it is determined by wheel offset.  Stock SW20 offset is 45mm front and back, regardless of the width of the wheels, if you retain this offset the track will remain unchanged.

 
If you run 45 offsets front and back with 6inch wheels front and back the outer edge of the front wheels will by half an inch further out then the outer edge of the rear wheels on each side on an MR2. Take a measuring tape and measure it. Also your car won't handle great with this set up for obvious reasons. At the very least the outer edge of the rear wheels need to match the outer edge of the front wheels on a mid engine car.
 
Anyway for the purpose of what is fitted for this memeber the tyre store has fitted the right tyres for the wheels. They will be absolutly fine driving on the street with them.

Guys
She came to see me saying here rims are 6 inch wide all round no idea on offsets
So I asked her two questions how does she drive she answered not like the rest of us do she is a very passive driver does not push it,
Number two how much extra were the tyres
Now
For an extra 10mm either side is not worth 70$
Yes it is risky with an mr2 but driven careful you could drive it with anything my mate had 185s all round on stockies when he bought his didnt change them for months.

Also the placard in a mk2 says 195/205

If you guys want to get technical it's also illegal to be running under the load rating specified and I bet 90 percent of us are even I am..

In my opinion 10mm is going to make f all difference to her based on how she is driving the car

Shaz just be a grandma in the wet and you will be fine.

  Don't know if I like the grandma bit.................... , but thanks for the help
 
But as I said i didn't know any different until the weekend.  So if I start feeling like it's not holding in the wet I'll do something about it then.
Love my little blue baby.
 
Oh,    the colour I think is the "Nautical Blue Metalic" not "Aquamarine Pearl" 
Aquamarine sounded light to me so I googled the colours.  The book was still in the car too & it says Blue Metalic.

 

Rolling diameter is the dimension that will affect your speedo accuracy - the larger the rolling diameter, the fewer revolutions the tyre makes for the same distance (distance = 2 x pi x radius of the outer surface of the tyre). That is why there is the difference section on a 195 vs a 225 - to keep the same rolling diameter.

Yeah I know.  It's all good.  Leaving as is.
 
Such a nice day outside my window,  wish I was out there cruising around now .  Stretched my work to make it last at least a couple hours.  Just way too efficent.... lol

Wait......... Stop.......... No more suggestions...............  I had an epiphany this morning. lol
but....................
   The handling feels stable, I felt comfortable enough in the rain that we had last weekend & it's fun to drive.  So unless I start to feel like it's unstable, I'll stay with what is on it & change the rims & size of the tyres next time.

See you next time.

 
 
I'm sure if like the previous owner, you just putt around town you won't have a bother. Apart from having to check your speedo accuracy against a GPS (they are pretty well much within 1-2kph on the money) - I really hope that you don't 'start to feel like it's unstable' when travelling in freeway conditions in the wet on a corner, having to brake harder than you anticipated.
 
The tyre combination and the tyre track being narrower at the rear is unheard of here. Maybe you could take your car to a skid pan, that will give you a pretty good idea of how the Toyo TEO's in that size will work. 
 
Don't want to freak you out, but these are pretty odd cars being mid-engined handling wise. Toyota put the staggered tyre sizing on for a reason, and it wasn't to be 'hektik'

A skid pan??

a concrete track that they wet down so you can practice slow speed driving in the wet, controlling slides etc.
 
shaz at the end of the day going from the stock 205 to a 195 tyre on the rear isn't going to make the world of difference putting around town. my spyder is meant to have 185 fronts and 205 rears and I had 195's all round for quite some time. When I was driving it was ok, didn't feel unstable it was only my partner that often found the difference a problem, sliding it out around corners in the rain, but he pushes the car alot more than I do.
 
What I have learnt is everyone has opinions on the wheel sizes, all you really have to go off for yourself though is find the best match to size you can to the stock tyres sizes  on the placard. put the data in those tyre calculators and work it out. I use this one myself http://www.miata.net/garage/tirecalc.html
 
When I put the Series 2 wheels on my spyder My partner looked up and match some common sizes to our stock size wheel according to the placard, I did this because the series 2 wheels are 15/16" combo unlike the stock 15" all round and they use a massive tyre on the rear. If I had have put the correct series 2 tyre on the speedo would have been way out as the diameter change is about 25mm due to the larger tyre/rim. The reason we matched them to the stock size rather than going the s2 tyre is because the speedo drive gear in gearbox is matched to our stock wheel placard, not matched to the s2 wheel size. But everyone was saying I was a fool and didn't know anything, I was doing it wrong etc. But my partner knows 100%, and with the odd size he chose the speedo is 100%. Just sharing my experience on the matter.
 

Hi Shaz,
As a sister female owner of an SW20 (1994), and having just been through a similar experience myself, I understand your frustration with all the technical jargon.
Don't give up, you will want the best for your baby, now that you have it!
Putting it simply, use the correct width and profile percentage tyres recommended for the 15" wheels that are original on the MR2 tire and wheel calculator. Your offsets for your current rims must be OK, as long as you are not getting any scrubbing on suspension or fenders.
If you are running the same wheel width all round, stagger your tyre widths that suits your wheel width.......I have always gone to Bob Jane Tmarts and found their advice always sound - they will know what tyres they can fit to your width rims to stagger them.
I was running 7.5" width rims for 10 years and had staggered tyre widths so it is possible until you are ready to stagger the rims.
Of most importance to the SW20 is the load rating for the rear tyres......you should be fine with 15" rims, however if you choose to get new rims, best stay with 15" or go straight to 17" as you can no longer get the correct load rated tyres for 16" rims - believe me I have tried in order to get across WA rego pits - had to get emergency 17" rims to get the correct tyre load rating!! Expensive lesson!
The car's centre of gravity and natural characteristics to stay glued to the road depend on the correct tyres (and to some extent, the rims) that are specified to the car.........if you want it to look after you, you need to give it the correct tools.
Cheers, M
