I got myself a pair of R33 GTR wheels for my GTST with 245/45/17 on them.

They're snow/winter tyres since they came from Japan.

I like the size since the tyre diameter is 2cm more than the standard 205/55/16

It looks good I find and gives good riding comfort.

(have a lot of potholes and speed bumps here)

In your experience is 245/45 a good choice for your cars or gives 255/40 more control?

Size won't cause wobbley-ness, probably something wrong with balance or the tyre itself. I like the run the widest tyres possible, but since you have a GTS-t, I'd look at the guard to tyre clearance. Slightly taller sidewall would help with ride, so I'd stick with 245.

Difference between 245 and 255 isn't much, the tyre design/construction/compound would make a bigger difference.

Um. Wat?

20mm extra diameter is not a good thing. Hello speedo error. Hello taller gearing.

For all that.....there's nothing wrong with 245/45 as a tyre size in itself. It is neither going to be much better or much worse than a 255/40 in any real way. You'd be hard pressed to feel the difference in grip, firmness, sidewall flex, traction....anything. The 255 would be the better choice just for being closer to the right size (rolling diameter), that's all.

If you leave them on there 'til they wear out, and you want to go for wider tyres that still retain some of the extra sidewall height, you could probably squeeze a 265/40 onto 9" rims on that car. Gains you a bit extra rubber on the road and half the extra sidewall you have now.

Alright,

Thanks .. I was just thinking since 255 and 40 profile has smaller side-walls it would make a a real world difference

(just by using the link I provided in my first post)

I have the 245 on right now and clearance wise it seems ok

Hi!

Speedo error seems no too bad.

(that's compared to the standard GTSTs)

Look here:

And 3% longer gearing seems to be an option,

Here's how it looks at the moment:

I run 265's on the back on 9" rim. I'd like to give a comparison to other size tyres but the last time i ran different size tyres they were 32 GTR tires, about 225 wide and rather old. Also car was stock and I ditched them about 4 months after buying the car

If you want to wait till you wear the current tyres out, fair enough. But go the 265's if you wont run into any problems with rubbing. I think mine are 265/35's but cant say 100% and too lazt to walk 4m to the car :)

Also, winter tyres won't be so good in summer eh.

Haha ..

Actually these tyres are very soft and traction is horrible if not scary!

Makes for a good show though ;)

That's why I need to change them but they're okay for getting an idea about sizes / clearance

(since the whole debate)

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
