Ive been searching for a while but cant get a proper answer,

I have an r33 gtr skyline, and have new wheels to put on it, now I have 2x new Achilles 123s semi slick tyres 265/35/18

I also have another pair of new Achilles 123s semi slick tyres also in 265/35/18

BUT the difference is 2x are circuit version that are 4.8mm tread depth new, and 2x drift versions that are 8mm tread depth new

Would this make a significant difference to my attesa? Ive read on some forums it would make a difference, some that it wouldnt as they are both the same size tyres....

appx 5% leeway before attessa picks up rolling diameter differences.

It's the rolling diameter and not tread depth.

watching a similar thread on here ATM and peoples opinions in there :)

Edit: Sorry. The answer to your question is NO.

Real world experience, not hypertheticals.

    • Bummer...yeah i "need" something to "ease" up the work and for my driving it would be enough.    Iam counting the tune "without" turbo. I do not mean "cheap" like something from Temu around 200 USD, "Cheap" is something around 1000 USD? 
    • Starter motors used to use the weight of metal (magnets) to provide torque. Now they use (more) current instead. This. It's completely normal.
    • So thing that had me stumped, but I think is OK....is that when it was up in the air, in neutral I had it running to bleed to coolant while I put the wheels back on. I noticed the rears were turning (slowly) which I'd never seen before 20250928_163512.mp4     Because there had been an issue with clutch slip due to pedal adjustment on the dyno, I assumed there was still and issue so spent some quality time upside down under the dash adjusting the pedal....but no matter what I did the wheels still turned in neutral. Even disconnected the master cylinder to pedal rod and same. In despair, I even removed the clutch slave so there was no chance of any preload causing it.....still happened. So either: 1. Something is not right in the bellhousing, or 2. Its a thing sometimes with cold, thick gearbox oil Internet says it might be 2, I hope so!
    • OK, few more things sorted and it is ready for a shakedown on 10-Oct, with one weird thing. Changed the run in oil and filter for the good stuff. 8l came out, about 8.5 went in with filter so that looks all good. Changed the starter (again), this time for a brand new one, works good. Interesting that the Taaaarks one is shorter than factory but spins harder, I guess electronics have moved on a little in the last 30 years. Will be nice to have a bit of extra space under there. Put the timing cover back on, and noted where the cam gears were set as a record.  Will need to double check the timing but it is pretty close. Also put the coil pack cover and intake snorkel back on. Exhaust Inlet Changed the water out for coolant, bled up nicely. Removed the rear brake pads (well worn factory sumitomo ones!), gave the hardware a good clean and reassembled. I've put bendix XP on the back again because the price is excellent at $150 a set and they worked well on the V37. Front pads have plenty so no issue there
