205/50/16 / 235/45/17 A052 200TW Tires

Anyone tried running these?
There seems to be almost zero talk about them on this forum, but from what I've read they could be the next 200TW street tire to have, surpassing the Re71r's.
They supposedly grip better, don't heat cycle out as quick, are more confidence inspiring/communicative, and quieter on the road.

I've seen mixed reviews on if the 205/50/16 tire size will fit, due to height on the Elise.
I have LSS wheels
I will be running about -3 degrees camber up front, the current 205/45/16s seem to have no problem fitting.
and I'm not afraid to fiddle with different spacer sizes to make it fit.
On BWR Double adjustables and my right height is slightly lower than stock.

Also a bit worried about turn in with a 50 profile front tire, but supposedly these feel more like a race tire, so I'm assuming the stiff shoulder on the light car will be fine.


This guy certainly likes them, saw this video and started researching them and noticed they were available in Lotus friendly sizes:

In my experience (they came on the car) a 205/50-16 will rub quite badly in the front on the light housing, even at stockish ride height.

How about a 215/45/16 Rival S 1.5. It's a hair shorter than the factory 195/50/16s.
The Rivals seem to wear a bit longer and turn similar lap times, plus the 215 might be a bit squeezed on the LSS wheels, but I'm not AutoX'ing the car, so transitions are less important than outright grip. Trying to maximize what I can do on the LSS wheels, before likely going to a 15/17" setup.

I'm having bad thoughts about putting Rival S 1.5s 215/45/16 up front and 235/45/17 A052s out back... tire sizes on this car create a frustratingly limited number of choices.

The R888Rs haven't been bad, but they haven't been that great either in all capacities.

Whats wrong with Re-71R in 205/45-16 245/40-17? Car is VERY neutral and easy to drive with these on with any spring rate I have tried.
lotus90, me73 and SS Lotus Elise like this.

Nothing wrong with them, but I would say the same about the R888Rs. just trying to maximize what I can put on the car.
Also some minor quibbles I would be a bit concerned with about the Re71Rs are tire life (heat cycles mainly) and while it's silly, the RE71Rs seem to run narrower tread widths than other similar tires and I already think the 205/235 R888Rs look a bit thin on the rim.


I like that bulging sidewall look... totally not practical to lap times but to me visually it defines the stance/look of the car almost as much as ride height and rake.

IMO there is no "heat cycle" problem and as far as I can tell the RE-71R are faster on the track then the R888R. I haven't run them back to back but I see enough of both of them on cars at COTA. Send me your R888R when you are done with them and I will back to back with with high HC RE-71R's and we will all have an answer after all

Or do you have aim G-Force data?

Negative on that. i just use harry's lap timer but the car's never pulled more than 1.1G. The track has one high speed on camber sweeper that you can peak to 1.3 maybe 1.4 but without significant help from the track angle 1.1G seems to be the limit.
This seems low, and even figured the tires were already falling off but another local Lotus owner confirmed he's seeing the same general numbers on that track with those tires.

Any idea what you're able to pull with the Re71Rs? I don't know if you ever track those tires or if they're just your street tire.

Canaan is a very good local track that I use for testing. Best I've done is mid 1.08s. Thats faster than 90% of the street driven cars on that track. The owner of the track has an ariel atom that he can clock 1:05s with. 125 Shifter karts do it in around 58 seconds. Thats the only analog I could give you for what would be considered fast.
My goal is to get down into the 1:05 range, and if those R888Rs are as worn as I think they are, the right 200tw tires might get me into the 1:07s or help me crack the 1:06s alone, and I still have a lot of work to do on my driving, plus there's zero aero on the car now.

So the 052's are the new hotness and really are a successor to the 048's. They are the only tire out right now to rival that of the 71R's. They're incredible, but sadly, I tried this in the exact config listed above, and just like the 48's, they tend to run wide...I rubbed EVERYWHERE (in track mode, did not test at stock heights)

So I went to the tried and true R888R's and got those dialed in nicely. There's just something about running these crazy 160/180/200TW "street-R'ish" type tire that I love...its too bad because I wanted to compare them to the 71Rs. (I've raced with RE's since the RE11's were new, they are imho, the best street tires available)

Side note, a friend of mine ordered these 052's for his Porsche at the same time, and had no issues so I was able to get a mild comparison. He's been running 71Rs and Cup2's for a while and said these felt better than his Cup2's...Food for thought!

Ughh... buying tires for the Elige platform is frustrating. I know these tires would be killer on this platform. I reached out to Yoko corporate today to see if they were planning on releasing more sizes at any point in the future.

225/245 Rival S on 15" miata wheels with a 1" spacer rear and 1/8" front. (I think this would fit but not 100% may need slightly less rear spacer.

Why not just go with cheap ethos wheels at that point, would require a lot less spacer.

Well for one the ethos only come in 15x7 don't they? Good luck running a 225/245 tire setup with 7 inch wheels all around...

I really dislike the look of the 6ULs, otherwise the'd be an obvious choice, even paying for the lotus specific offsets. How about custom aluminum racing weels.

Anyone find a aluminum racing wheel that would work, or a company that will make them custom for "somewhat reasonable" prices

There are 6000 miata wheels. On goodwinracing there are 9 options in 15x9 alone. Bogart is the custom wheel of choice AFAIK.

I am partial to the Storm S2 in goldish

In case you haven't heard yet, even Lotus is replacing their OEM AO48 with the new AO52 (and also the old AD07 with the V105):

Tyre Dimensions/Specifications

Yokohama V105:

The front tyre size and loading is increased to 195-50 R16 84W as compared to the original AD07 size of 175-55 R16 80W. The rear tyre size and loading remains the same (225-45 R17 91W). The sidewall/tread pattern for the V105 specification tyre is different as compared with the previous AD07 type. The new V105 specification displays ‘MO’ (Mercedes) for the rear tyres. There is no manufacturer’s code displayed on the front tyre sidewall.


Yokohama A052:

Both front and rear tyres sizes are the same as the A048 specification tyres they replace, but the loading values are increased from 84W to 88W for the front tyres and from 90W to 94W for the rear tyres. The sidewall/tread pattern for the A052 specification tyre is different as compared with the previous A048 type, which also included the ‘LTS’ branding displayed on the tyre sidewall. There is no manufacturer’s code displayed on either the front or rear tyre sidewalls.


I have no info on the front tire size of the AO52, but I'd assume they stick with the 195/50/16.

If I die, my biggest fear is that my wife sells all my toys for the price I told her I bought them for...

15x8 and 17x9 team dynamics are a good choice. Just need a 3mm spacer for front and depending on the rear tire no spacer. 205 50 15 and 245 40 17 re71r. Better tires, less weight, more rake!
