Hi, so I will be soon I need of 4 new tyres

My car is MK3 Octavia vrs 2.0 TDI on standard suspension but I do have 15mm spacers on front and 20mm rear. 

 

Bought this car about 2 months ago and urrently running Pirelli pzero but they are 5 years old and basically no grip under wet conditions.

 

I live in Ireland which is filled with speed bumps and some potholes, currently running 225/35 R19 but wanting to get something to absorb better the potholes etc. 

 

I seen that most get the 235/35 R19 version. But I'm wondering if I can also go up with the higher sidewall like a 235/40 R19 tyre.

 

Has anyone got them sizes on their car with spacers included?

Or would it be better if I get 225/40 R19 Instead 

 

 

  

The change in profile has a bigger affect to height than the width.  The width will give you most of the protection you need.  Another option would be to change to 18s which would give you an all round more comfortable ride while not impacting performance.

I dont think you will notice any difference to be honest

If you don't want to go down to 225/45R17, then slightly oversize 235/40R18 7.5Jx18 ET51 5/112 57.1 wheels should give a decent level of ride comfort. These tyres are 10mm wider than the standard 18" tyres, ie. 225/40R18. Notice in the chart below, that 235/40R18 would keep the gearing close to standard. 235/40R18 fitted to 7.5J rims would give much better ride comfort compared to 225/35R19 fitted to 7.5J rims. To get the 235/40R18 to feel as hard as the 225/35R19 you would have to overinflate the 235/40R18 by at least 6psi...and considering its easy to notice a 3psi difference, this is twice that difference.

 

Outside diameter of tyre

225/35R19 640.1mm

235/40R18 645.2mm (0.8% bigger outside diameter compared to 225/35R19)

235/35R19 647.1mm (1.1% bigger outside diameter compared to 225/35R19)

225/40R19 662.6mm (3.5% bigger outside diameter compared to 225/35R19)

235/40R19 670.6mm (4.8% bigger outside diameter compared to 225/35R19)

 

Alloy rims from the Skoda accessory catalogue can be ordered from any VAG parts department by quoting the relevant OEM part number.

I just slapped on 245/45/19s and it's as comfy as you can get 👍

I think it's worth finding a tyre with sidewall protection. I'm really pleased with Goodyear Vector 4 Season tyres as they come with the sidewall protection and cope well with rubbish roads, terrible road conditions which we have here in the Scottish Borders.

Thats a pretty large increase in diameter of your wheel, just be mindful your speedo will be reading low now.
