My car currently runs 215/45/17 on the front, and 235/45/17 on the rear. My rims are 17x7 front, and 17x8 rear.

Im of the understanding that i could fit 215s all round, but is there any tyre performance issues other then those associated with reduced surface area, that would stop you putting a 215 on an 8" rim?

That's a first!! I never heard of anyone wanting to go smaller in the rears.

I have F:245/35/19 and R:275/30/19. Have had no problems and just some minor rubbing of the plastic gaurd insert, as i turn up drive-ways. But the car does have a set of Tein suspension, which are relatively stiff.

PS: Gaurds have NOT been lipped, as i am not prepared to respray the car when the paint cracks.

Reason for wanting to go 215s all round was firstly im able to get some R compund track tyres for good $$$, but they are 215.

The guards on my R32 have been rolled and still anything wider then 235 on the rear rubs, and anything wider then 215s on front rubs.

I have had a set of work rims on the car with different offset that allowed 255 on rear and 235 on front without rubbing, but the 255s sat outside the rear guards, looked too 13B drag Corolla for my liking.

Hi Guys, tyre sizes do vary between brands, even the same brand has anomalies. We have 235/40/17 Yokohama A032R's on the front that are 239mm wide and 245/45/17 on the rear which are 243 mm wide. So 235 versus 245 should be 10 mm wider, but they are only 4 mm wider.

Oils ain't oils, Sol.

I have 235/40/17 on the front and 255/40/17 on the rear...

I have noticed that the front tyres wear unevenly now...

The inside 1 inch wearing bald while the majority of the tyres are chunky as...

Anyone else getting this ?

I am told that sometimes Skylines do this, or that wide tyres cause this...

Also finding that the guard-liners are wearing against the front tyres somehow...

Thing is, I've had it for years and its only started doing this in the last year...and I can't figure out if it is worn suspension or my driving on corners...

The initial indicator I noticed in the area was that the guard liners pop to the outside of the guard lip, and I have to sometimes push them back in behind them...

I'm interested to find if others have any similar signs...

Last time i got a wheel alignment i started going thru front tyres...too much camber.

Didnt notice any difference either by feel, lap times, or in consistancy so have dropped some camber out of the front. Tyres seem to be wearing better now.

You R33 owners are spoilt, just like my friend in his 200SX, your guards swallow 18s, even 19s, or nice and wide 17s.

What you mean OR, i have the best of both: 19" x 8" rims all round with F:245/35/19 and R:275/30/19. :D :shake: :) :shake:

Hi PuppaDuck, tyres wearing on inside = too much negative camber or incorrect toe settings. Puting wider (or narrower) tyres on should not affect the suspension geometry. Either way have it checked. Toe should be set at zero or slightly toe out. Camber is a little more tricky as it depends on your driving style. Anything more than 1 degree negative on a road car can be a problem.

If you like the handling feel of negative camber, try more caster instead. All of the advantages, but no increase in inside tyre wear.

Hope that helps.

Thanks SydneyKid...

I'll put this to the next guy I go to for a wheel alignment...

I have no personal choice nor do I know what to ask for...

But if I can get front tyres to last longer than a year by wearing even then I'll be happy...

Maybe he was put off by not knowing what settings to put it on cause the R33 isn't in his book...or perhaps he wasn't sure about the HICAS...

Hi PuppaDuck, since HICAS is rear steering I have no idea why that would effect what he thinks should go on the front. I'd find a better wheel alignment shop. We use Whiteline (Wedge) at Minto or Heasmans (Doug) at Sydenham. East Coast are also OK.

The "local tyre shop" is generally a waste of time.

Hope that helps.

    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.
