Flashback Posted August 18, 2016 Share Posted August 18, 2016 Hey guys, Just as it says what happens to your handling as you go through sizes and widths of wheels? Currently running stock 18 inch GT wheels but looking at some nice JR21s from Tarmac. They are very different at 19 x 9.5 / 11, so will look great but not sure what will happen to the handling. Any pointers /past experience welcome our also any handy links to read up on the subject would be great. It's a daily driver so want to be sure it looks good but doesn't become less fun to drive.

Banz Posted August 18, 2016 Share Posted August 18, 2016 I got 275 19" tyres, they are difficult to get around work car park due to the tight corners. Steering is really heavy, but I bought the car like that so I do't have anything to benchmark against. Quote Link to comment Share on other sites More sharing options...
StevoD Posted August 18, 2016 Share Posted August 18, 2016 (edited) aslong as you put wider tyres aswell you will more than likely find more grip although 18s for go 19s for show seems to be the motto Edited August 18, 2016 by StevoD Quote Link to comment Share on other sites More sharing options...
Jetpilot Posted August 18, 2016 Share Posted August 18, 2016 On the roads the most noticeable difference will be it feels a little firmer/harder because of the lower profile tyre, actual handling wise i doubt you will notice. Quote Link to comment Share on other sites More sharing options...
Ekona Posted August 18, 2016 Share Posted August 18, 2016 You'll find the car will stop slower, accelerate slower, and feel heavier through corners due to the extra unsprung weight. You'll also likely have a harsher ride due to the thinner sidewalls, along with the extra weight. However, you will have more grip and let's face it, they look better! Totally your call, and Stevo's last line says it best. Quote Link to comment Share on other sites More sharing options...
docwra Posted August 18, 2016 Share Posted August 18, 2016 I used to run 265/10 and then 255/10 on the front of mine and it handled like a dream, I wouldnt want to go much wider though. 19x9.5 will be fine 1 Quote Link to comment Share on other sites More sharing options...
StevoD Posted August 18, 2016 Share Posted August 18, 2016 265/10/19 damn that a tiny tyre Quote Link to comment Share on other sites More sharing options...
GMballistic Posted August 18, 2016 Share Posted August 18, 2016 Everyone has an their own opinion obviously but.... With my old 2003 Nissan 350Z I went from the standard 18" Rays alloys (225/45/18 front & 245/45/18 rear) to 19" Rotas (245/35/19 & 275/35/19) ~ I felt the handling was improved as far as traction "off the line" and stability at higher speeds through corners was concerned. As Dan mentions though I know due to the weight differences of my old alloys/tyres versus my new alloys/tyres realistically the car should be accelerating slower & braking slower but honestly it must have been so minor as I really didn't feel the difference in that respect. Maybe I'd have noticed it being 0.5 seconds slower to 60mph if I'd had it timed on a drag strip or something but in real world driving (A-B, social, domestic & pleasure) it just really didn't make that big a difference at all imo. Forget the "18's for go & 19's for show" rubbish imho and simply put what you like the look of on your own car ~ as long as it's round it will always go. 3 Quote Link to comment Share on other sites More sharing options...
nissanman312 Posted August 18, 2016 Share Posted August 18, 2016 Are these the set he advertising on Facebook ? I also like those but wondered the same Thing is I already have 19s on the 370 so hoping to not notice to much difference Quote Link to comment Share on other sites More sharing options...
Flashback Posted August 19, 2016 Author Share Posted August 19, 2016 Haha probably wouldn't feel much different with 439 horses under you GM! Quote Link to comment Share on other sites More sharing options...

I agree mostly, what fractional amounts you "may" theoretically loose on braking and acceleration and I am talking probably 100's of a second at best you will make up in increased grip levels from wider tyres and certainly not noticeable on the road. The 350 on track though does feel vastly better on 18's, mostly when it comes to quick direction changes and steering input and for that reason alone i would prefer them on track. Whether out and out pace between the 2 vastly different I would be surprised with us average drivers Edited August 19, 2016 by Jetpilot Quote Link to comment Share on other sites More sharing options...

You're right, maybe it's only 100ths you lose, but it's VERY noticeable in terms of feel. Everything feels heavier and clunkier, and at low speeds like you find on the roads is where you notice it the most. Heavier wheels just make the car feel lumpier and more weighty, which isn't a trait I'd want. Even the difference between Rays and OEM 18s was huge, when swapping between the two. 1 Quote Link to comment Share on other sites More sharing options...
StevoD Posted August 19, 2016 Share Posted August 19, 2016 my 19" grids made the car feel very un reactive to inputs compared with all the 18" set ups i have run over the years Quote Link to comment Share on other sites More sharing options...

Must stop agreeing with Ekona .......... I ran my 350 on 4 different sets of wheels and my 200Sx on more like 10 and hes right, it is noticeable, particularly on the front end, more than 100ths of a second anyway. If youre only focused on performance then the smallest, lightest wheels is the only way forward,. Quote Link to comment Share on other sites More sharing options...
GMballistic Posted August 19, 2016 Share Posted August 19, 2016 Haha probably wouldn't feel much different with 439 horses under you GM! Well when I changed my alloys from 18's to 19's the Zed actually had a dyno'd 294Bhp, ...make of that what you will, but yeah alloy wheel size doesn't make too much difference in a straight line imo when you've over 400Bhp pushing you down the road.

taybo Posted August 19, 2016 Share Posted August 19, 2016 So are there any wider wheels that are as light as the Rays? Would like to get 10.5 at the rear and 9.5 for the front. I wish sellers would give the weights in their wheels stats! 1 Quote Link to comment Share on other sites More sharing options...
Jetpilot Posted August 19, 2016 Share Posted August 19, 2016 Yes, but your looking at loads of money for new, £1k plus 2nd hand unless you get lucky. Quote Link to comment Share on other sites More sharing options...
Stan350Z Posted August 20, 2016 Share Posted August 20, 2016 Why don't more people do what Nismo did and put 18s on the front and 19s on the rear? Best of all worlds surely? Does there need to be significant changes to suspension setup? Quote Link to comment Share on other sites More sharing options...

So it will be slower around corners, but you'll have more grip, but it will feel less responsive but handle well still? Quote Link to comment Share on other sites More sharing options...
Ekona Posted August 21, 2016 Share Posted August 21, 2016 More grip when using power to exit a corner yes, but slower steering inputs into and out of the corner. Quote Link to comment Share on other sites More sharing options...
Ekona Posted August 21, 2016 Share Posted August 21, 2016 And that grip will be blunted by the extra weight, so you'll actually be slower. Quote Link to comment Share on other sites More sharing options...

BobbyZ Posted August 21, 2016 Share Posted August 21, 2016 Generally speaking, more rubber on the ground will give you more outright grip, but the extra unsprung weight will make the car less responsive and will hurt the ability to control the wheels over bumpy surfaces. It's not possible to predict whether it will make you faster or slower without back to back tests of the specific set ups in question around specific cicuits, so I'm not sure why people are trying to do so. It will also depend somewhat on driver preference / driving style. Quote Link to comment Share on other sites More sharing options...
