scotchegg Posted February 11, 2012 Share Posted February 11, 2012 Would be great to get a few noob answers guys and perhaps make this sticky? I have a 350z black with scuffed stock wheels at the moment with a desperate need for new tires! CS will vouch for this. So , my options are.. repair stock 18" wheels and buy new 18 tires. Buy new 18" alloys and New tires. buy new 19" alloys and New Tires. I have no ideas on the pros and cons and costs of this so would love some advice. Questions at the moment are.. What are the benefits of 19 over 18, is it just they look bigger? Are there any cons of going to 19 inc? Does the alloy size restrict my tires options? What do terms staggering, spacing mean, and anything else i need to be aware of when making this alteration? is there a good alloy place in birmingham to visit for styles, fitting and advice? thanks for any help on these questions. pete Quote Link to comment Share on other sites More sharing options...
Dblock Posted February 11, 2012 Share Posted February 11, 2012 I'm going on the assumption you have rays. Then 19s will be heavier. 19s suit the care better. As your buying new alloys you can buy ones you like so improving the look of your car. If you get the 19's in a decent size you can get more grip with wider tyres and you improve looks and stance. Tyres cost a little more though. You can get the right offsets if your getting new weeks. Best place would be CS. Quote Link to comment Share on other sites More sharing options...
M13KYF Posted February 11, 2012 Share Posted February 11, 2012 the rays are pretty light if your looking at performance 19's are good for looks Quote Link to comment Share on other sites More sharing options...

Off the top of my head - if the 19's are wider you'll have more rubber on the road so may help with traction (depending on the tyre), you'll also need to try and keep the same rolling radius with a low profile tyre (which is likely to improve handing as there is less movement in the tyre wall - if using decent rubber - will also make the ride a bit more crashy as low profiles pick up more lumps and bumps in the road) so ultimately they wont actually be any bigger (suppose you could keep same profile tyre and roll arches but not sure what the max you can fit in is - fiddling with rolling radius can spaz up the traction control sensors). Staggering simply means 2 different sized wheels front and back (if memory serves you only find this on RWD cars so they can get the power down a bit better). Spacing means sticking a disc of metal between the hub and the alloy to give a better aesthetic look to the car - many people who've had them on report adverse affect on handling although I can't say I've really noticed it (then again I wouldn't say I'm a serious driver). Yes you do need to know something else - you need to tell your insurance company and the more generic 'big boys' can be a bit retarded about them and either refuse to insure or put it on as some sort of suspension mod which costs a fortune to insure.

ben@RARE RIMS Posted February 14, 2012 Share Posted February 14, 2012 Spacing will have the same effect as having a lower offset wheel - it does the same thing The only point where spacing has an adverse effect will be if you dont have hub-centric spacers, which means the wheel will have nothing to locate on the become central. This can lead to wheel wobble at higher speeds. Staggered wheels for most people means running a wider rear wheel than front. For example 2 of the most popular 350Z options are: 19x9 ET20 Front. 245/35/19 Tyre (usually falken FK452) 19x10 ET20 Rear. 275/35/19 Tyre (usually falken FK452) Or 19x9.5 ET20 Front 245/35/19 Tyre (usually falken FK452) 19x10.5 ET20 Rear 275/35/19 Tyre (usually falken FK452) Depending on your ride height and alignment, if you have an offset much lower than this (lower offset means the wheels stick out from the car more) you can start to have tyre rubbing on wheel arch issues. The can be solved by rolling the inner lips of the arches flat to give you more space, dialling in some camber, or using smaller tyres and going for the 'stretched' tyre look which I have to say doesn't tend to make you a huge number of friends on here Every tyre has a range of wheel sizes it will fit. They are usually faily generous, for example a 225/40/18 will happily sit on a 18x7.5 wheel or a 18x9 wheel and still be within spec. Whoever supplies you wheels should be able to help you with tyre options as well. 350Zs are a little sensitive to tyre sizing for their traction control. They have slightly odd sizes as standard, and like to keep the same ratio of front - rear sizing, so this is worth mentioning if you're buying from a non-specialist wheel+tyre supplier. 18" wheels are going to be cheaper for tyres, and cheaper to buy, along with being a bit lighter and give you a higher profile tyre so the ride quality will remain as standard. 19" wheels are a little more expensive, as are their tyres. They are a bit heavier, simply as there's more to them. They do however tend to suit the 350Z better than 18s, they arches are HUGE and 19s fill them better, and proportions suit better. I think that covers most things, if I have missed anything let me know and I'll do an edit - hopefully as a sticky this will be a handy post Quote Link to comment Share on other sites More sharing options...
sasha@lazytrips Posted February 14, 2012 Share Posted February 14, 2012 horses for courses, but I would highly recommend 255/35/19 and 285/35/19 if you're going for 19'' wheels. For some reason the 245/275 combo is taken as gospel round these parts though. Quote Link to comment Share on other sites More sharing options...
ben@RARE RIMS Posted February 14, 2012 Share Posted February 14, 2012 It depends on tyre brand to a degree, and the offset you choose - those tyre sizes I mentioned are just the most popular, we have done all sorts in the past Quote Link to comment Share on other sites More sharing options...
