 Cheers, I have them at 32, no wonder it skittles around!

 i’ve got mine set to 32Front and 30Rear.

 My rims are a stock 17"x7". The Mazda factory settings for the 205x40x17’s on a stock SE Turbo are 29# front and 32# rear.

As every other MX5 seems to leave the factory on 26# settings all round … take your pick according to the set-up. However, I would NEVER go down to 26# because they would be under-inflated according to my Sevice Manual, the Driver’s Handbook & the tyre pressure list in the door jam.

 I think we are discussing entirely different models; recommondations for NB tyre pressures do not apply to NCs and vice versa. They are entirely different beasts, with virtually no copmmonality. BBit like recommending tyres pressures on a Mini, based on what is done for a Jag.

 I did mention my model and went on to say ‘according to your set-up’; since nobody else mentioned a model anywhere! [:(]

 Hi, fair do.  My car is a 1.6 Mk2 runing on 17" OZ alloy wheels.  It just seems so “skittish”.  I had new suspension http://www.mx5parts.co.uk/product_info.php/products_id/1471 put on and then a wheel check at WIM.  Thats why I am fiddling with tyre pressures now.  Cheers Neil

 This is a very late reply but the question is still a very good question

i asked the sames thing today in three differant tyre fitting centers and not one person gave a good reply to the question 

of a 1999 mx5 with 205/40/17s

i have run mine or 25psi all round for the last twelve months and she seems to be ok

but is that the correct preasure ? 

i think it is just about right 

thanks

The answers are already posted. Since you are not using a standard Mazda size for your model how can you expect a “correct” answer from the tyre fitting centres?
