I found a set of SSR's in 15/16 that will fit. The rear does need a 5mm spacer though. All 4 wheels weigh only 40.4lbs. That's 11.2lbs (minus whatever the spacers weigh) lighter than the 16/17's. I would use 195/55/15 and 225/50/16 AD07's. How much could the extra sidewall weigh? Not 11lbs right? 195/50/15 is also available, that wouldn't be a better choice as far as handling goes, would it?

Thanks for your time.

Did you mean to say AO48s? They would fit and would give you a lot better grip.

If you want tires for the 15/16 wheel combo, why not take a look at the tires used by the Elise S2? 195/50-15 front, and I think 225/40-6 rear. They use the Yokohama AD-05/AD-06 (one is left side, one is right side). People who have compared them on the Miata prefer the AD-05/6 over the AD-07.

The A048 will have more grip, but probably won't be as pleasant a street tire. I'm not sure that they make it in the correct sizes, either.

I know they make the 48's in that size. It's just not what I'm looking for now.

I didn't know that people like the AD05/6 better that the 07. Over here the AD07's are reguarded as one of the grippiest road tires available.

I wasn't really asking about the tire choice, but the tire size in front. The 195/50 is a full inch less diameter. I wondered if that would be too small. Why would I go with a 225/40/16? That's way smaller that the standard diameter.

Thanks.

Because the 195/50-15 and 225/45-16 size combination was developed for the Elise S2 by Yokohama and Lotus. They are sold with the Neova AD-05/6 LTS designation to denote Lotus-specific tires. The 195/50-15 is apparently unchanged (Bob Hall formerly of Mazda claims that size was originally developed to work well on the Miata), and the 225/45-16 have some Elise-specific changes to the construction.

The one in-depth review from someone who has tried both the AD-05/6 and the AD-07 on his Miata said that the old model had quicker response.

It is interesting that the US Elise LSS tire sizes are exactly the same width and aspect ratio as the Neova set for the UK/Euro Elise, but with 1" larger wheel diameter. I wonder if they lowered the suspension and raised the fenders to compensate?

OK, 225/45/16 makes more sense. I think you just mistyped 40 instead of 45. Thanks for the link!

15"/16" wheel widths?

KuroiSport,
Can you please tell me what wheel widths you found for the 15"/16" combination? Also, what cars are they intended to fit (or how would I know what to order if you don't mind me 'borrowing' your idea?) Thanks!
I ordered LSS and was planning on doing as you are, only using 195-60 (15") front and 225-55 (16") rear tires for long distance touring. Goodyear makes an Eagle F-1 in these sizes. Not sure of size availability in other brands.

I found 15x6.5 +30 in the SSR Type C which is same wheel as the SSR Competitions offered in the US. They only make ONE 16x7.5 in the Type C and it's not even the right bolt pattern. I am going to use an SSR Comp 16x7.5 +42 and use a 5mm spacer. I found that size on Tire Rack on the Miata. The other "downside" is, the Type C and Comp don't have the same color options so I will have to get them painted.

I don't think 195/60/15 and 225/55/16 will be good sizes, especially with 6.5 and 7.5 widths. That's a lot of sidewall. The diamerter will be more than stock too. I did some more looking around and found out that 195/50/15 and 225/45/16 is actually the better sidewall. You guys in the States are really limited on tire selection. I can find most of the popular tires in the sizes I want for this car. Generally at lower prices too.

Umm.. Sorry.. No..

Those sizes are for the S1 Elise, not the S2. These tires were developed for the S1 after Pirelli stopped making the original speficiation Pzero's for the S1 Elise.

The S2 always used 16/17" wheels, it's the S1 that's on 15/16"

Do you mean don't use the 15/16's, or that particular tire isn't for the S2? I understand that tire was developed for the S1.

As a side note, I understand that the LSS steering rack is mounted differently than the standard one because of ride height. If I use the 50 and 45 pofiles in the 15 and 16, that will lower the car 1/2" but that would not effect the suspension geometry so I wouldn't have to adjust the steering rack, right?

Thanks again.

Sorry, I got confused about when the change to 16/17 wheel sizes happened. I'd assumed that the supersizing was done for the American audience based on something I read here. (Yes, right here on the internet, where everything is believed to be true by someone).

Running the 15/16 combo above would lower the car's height 1/2", preserve the front/rear width difference, and lower the gearing/raise the speedometer reading by about 4%.

A 195/60-15 and 225/55-16 combo would be about the right diameter, but I doubt that you will find many sporting tires in those sizes, and even fewer in both. 195/55-15 and 225/50-16 might be a good compromise with some availability of matched sets of sports tires (okay, maybe just the Dunlop SP9000)

205/50-15 and 195/50-15 have a greter selection of performance tires than 195/55-15...
