Hi All
I am thinking of upgrading my alloys to 19's but have no idea what the tyre sizes should be. Currently running the 18" Monza II so what would be a safe upgrade trye size for the 19's without rubbing?
-
I have 19s on mine with 8.5 width, 235/35/19 were on originally and were fine until lowered. So I switched to 225/35/19 and now I have no issues with rubbing.
P.S. If you are looking to sell your Monza II's, PM me :wink:
-
If 225/35 R19 88Y XL tyres fitted on 8.5 J x 19 wheels won't rub, then there's a good chance that 235/35 R19 91Y XL tyres fitted on 8.0 J x 19 wheels won't rub.
Depending on your country's laws and regulations, this may or may not compulsory, but it would be my strong recommendation that you buy 8.0 J x 19 wheels, and hence 235/35 R19 91Y XL tyres, in order to keep the load index at 91 or above.

From what I can gather, the laws here are pretty much the same as back home in the UK, but I definatelt see your point. I will contact the supplier to confirm wheel width and I will definately try and stick to the 235's for 19's.
Will the tyres have the same look as the 18" Monza II's with the 225/40 or will they sit slightly further out on the rim? The latter would be nice and hopefully give a bit more curb protection than the current tyres give.
swf7y, I will be looking to sell on the Monza's, they are mint with absolutly no damage to them. The problem is i am currently living in Cyprus and the car is obviously here with me. I know DHL ask for rediculous delivery charges bt I think FeDex are quite resonable. I will pm you to chat further.

Blinkers, sorry mate I didn't realise you were in Cyprus! :tongue:

Swf7y, just pm'd you.

Although the "235" in "235/35 R19" refers to a tyre's section width in millimetres, it actually varies from make-to-make & model-to-model due to permitted tolerances.
Also, the width of a tyre is dependent on the width of the wheel it's fitted on. For every 1/2 inch increase in rim width, you generally add approx. 5 mm to the tyre width, or subtract approx. 5 mm for every 1/2 inch decrease in rim width.
So in other words, you won't know for sure, other than by looking at other people's wheel & tyre combo or photos on the internet.

The wheels are actually 8.5x19 with ET45 offset. The shop also told me to go for 235/35/19's but I've got a feeling this might be a little to wide, especially as I am planning to lower the car.
I've seen the same wheels on another car and the guy was running 215/35's but they were streched and not practical.
Would 225/35's be any good?
Struggling to make the right choice!!! :undecided:

If this chart is reliable, it's apparently fine to run on 235/35 R19 on 8.5J x 19 ET45 wheels if you're only lowering it by 1 inch (25.4 mm).

But lots of people on the internet claim it will/will not rub when lowered, so very inconsistent. :huh: But almost all are unanimous in that an offset of less than 40 has a very high chance of rubbing. At least the wheels you plan on purchasing have an offset of 45, which helps somewhat.
If want my recommendation, I'd get the 235/35's, and just research your brains out on what suspension kits won't rub. It would be better to risk not being able to lower the car more than 25 mm (again, more research) rather than risk using tyres with a lower load index IMO.

Thanks Hyperspace, that is some brilliant info! I think I will fit 235/35/19 as this will keep the same load bearing and I just hope I can find a suspension set up that will keep them from rubbing.
There are just so many different opinions that I think this going to continue to be a grey area and only trial and error will give the answers. I'm gonna have a word with my local tyre shop to see if I can get them to try a couple of different tyre brands as I'm sure this will play a major part too. I might just wait to lower the car first and take it from there?
