Tree I'm getting rid if my gtr/gtst
Getting me a set of enkei rpo1s :D

I went to Tyres and More about 2 weeks ago and asked about the Toyo T1R 225/50/15, from memory I think they were about $180 a tyre.

Try Yokohama es100 heard good things about those
Gt radials I use champiro hpx's
But not sure if able to get them in a 15 inch

Apparently the Yokohama es100 were discontinued quite some time ago...there has been quite a few good things said about them though on an MR2, that's a pity! Their replacement, the s.drive doesn't come in the required sizes either - no 225/50R15 for the rears.
The Champiro's don't appear to come in the correct sizes either :(

I think BF Goodrich G force (or some variant) is another you can find in 225/50/15

There definitely should be a sticky somewhere for this sort of thing! Took a look at the G Force Sport, they are the correct sizes and the RRP isn't all that much. The only problem I could find on them is apparently they are quite noisy. Any idea how they perform?

The problem with tyre reviews is that they are reviewed on different cars with different sizes, and different drivers. Some people love 'em, some people hate 'em, so you can't really tell.

Absolutely correct, so many different ways to drive, what people like and such. I attempted to narrow it down to people with MR2's who had commented on what they thought of it. Thanks for the evaluation of the T1R's, they sound like pretty good tyres then once they've had some K's on them.
 

Sorry no real world experience with those BFG's only what the reviews are:

Lower score rating than T1Rs but if they are cheaper I might get these down the road (or whatever is cheapest lol) once my A048s are finished in few months time or less. Will post reviews.
I guess it's difficult to really evaluate the tyres by others reviews but it gives me a general idea hehe. For example this is not the first time I've come across someone saying T1Rs have "floaty" or soft sidewalls (soft tyre in general). Need something that will hold up to bit of track abuse. On the positive side they done an article for testing T1Rs vs semi's on that same site so it must be good enough for the street?
Oh and to answer your early q's, running 205 in lieu of 195 will reduce the "stock understeer setup" and yeh ideally you'd want same tyre tread pattern for a sensitive car like the MR2 (as well as rim diameter) according to my tyre/suspension shop. Saying that reddtarga seems fine and I recently was at the track with a guy who ran different treads (front vs rear) and he did pretty well.
Gatesys - slowly transforming it into a familiar race car :P ?

Was that guy me? Ahahahahahahaha
Bob Jane and gt champiros for the win :p

Here's hoping ahah nah one if them is cracked :( and I can't find a gtr for cheap so enkei here I come

I have run Goodrich G force sports on the rear.
Great grippy tyre with stiff sidewalls and great handling, much more stable than T1R's, but that's all academic since I have been told by several tyre places that like many good 225/50R15 tyres for an MR2 that were available in the past, they are no longer made. (But if anyone can find any, let me know and I'll immediately grab some).
 
I am afraid that some time in the future nobody will make that size in a road tyre, and we'll all be running R comps.

Or for the loss? Ahahah
:p

I went looking for them after they were recommended, the website lists the 225/50R15 as a size but unfortunately I haven't found anyone that sells them, it's all 225/60R15 :(.

The tyres that came with the car when I bought it were GT Radial Champiro 50's and I had no real complaints about them! They did seem a bit noisy, but never had any issues in wet or dry. Another tyre that isn't made anymore and the successor doesn't come in the correct sizes.
 
After all this looking around, if I'm dead set on having the same tyres all round then I'm down to two tyres that are actually sold/can fit the car: Toyo T1R's and Falken Ziex 912. From what I read about both tyres before, I'm leaning towards the toyo's for an MR2.

I found a lot of the tyre manufacturers/wholesalers websites are out of date and list tyres that are no longer made.
 
I believe you just have to specifically ask a tyre retailer what they can actually get for you, and they'll probably have to phone up their supplier to find out.

Can I suggest Kumho's they have a large range, but you may need to have slightly different tread pattern between front and rears, but have a chat to you tyre dealer......I have recently acquired Kuhmo Ecsta KU21 for both front and rear and found them to be fantastic.......they are not a track tyre, but great for general driving - recommended. :-)
