I've been lurking around the multiple tyre threads for some time. The time is nearly here for me to renew the current tyres with something more comfortable, but not spoiling the handling. I'm potentially looking to replace-
OEM 195/40/R17 Side wall height 78mm
With
PS4 195/45/R17 Side wall height 88mm

As yet I've not seen this done (hence the new thread). To put this into perspective the side wall height on a golf with 18" wheels 90mm, so this isn't so crazy and shouldn't throw the speedo out too much (+2mph @ 70mph). I had considered slightly wider tyres (205/40/R17) on the fronts, but I'm leaning towards keeping them all the same. The PS4 is widely viewed as a comfortable tyre. People have gone with higher profile tires and not had any rubbing, so this shouldn't be a showstopper.

Anyone done this before with this size or tried staggered tyres sizes?

I’ve trialed a few setups and I’m running a stage 2 but here’s the rundown on wet/cold weather: Michelin Pilot Sport 5 205/40R17 (all round) this is optimal for handling grip, even first gear it will not spin up in wet unless surface is smoother. For Summer/hot weather there’s 3 different setups: 1. Standard tyres on rear with a Michelin Pilot Sport 4 up front, this is really more a speed set up as the stock tyres are Bridgestone 195/40R17 having thinner tyres on rear allows greater speeds(this set up is cool come winter cuz the rear end comes to life. 2. Michelin Pilot Sport 4 rear with Nankang NS2R up front, this is when the car became a legit go kart and I mean it went round corners like it was an f1 car, warning you lose straight line speed as they’re a semi track tyre and they’re very slippery in the wet and cold.3. Michelin Pilot Sport 4/5 all round, again this set up is probably the best all rounder set up with supreme grip and speed. I have trialed all these setups and got the information from a YouTuber can’t remember his name but he trials tyres and I got in contact with him. Hopes this helps.

Thank you for this. It's good to see you're trying something different. I expect I'll probably be going with the alround option of PS5 on all 4 corners. I have eibach coilovers fitted and I'm finding the car very well balanced, so for me I think I'll try this first, but I did consider mixing the tyres front to back.
Stage 2 must be fantastic is this little light car.....one day!

Your right. Luckily they are repututable companies, so fingers crossed. I'm not sure if they are painted or powder coated either, but I'll just state that it looks like a finishing process has been missed. That way it takes "perception" and colour tolerance out of the equation.
When I do get these wheels on they will be the same width and offset as yours Aitch, so I will tell you with confidence if they rub on the pro st's👍

Plenty of roads in far-flung areas the UK with improved roads from EU money, but sadly no more! Luckily the UK has become so rich from Brexit, that we'll all be buying private helicopters, as soon as our Brexit bonus cheques come through the letterboxes. Hahaha!
Or maybe paying through the nose for imported new tyres... :)

Just an update on the wheels the I ordered. I now have a matching set (remember one was a different shade - replaced). I ordered 4 tyres but blackcircles only sent the garage 2 tyres! 2 more are on the way, so all will be well.(never previously had any issue with blackcircles, always been very good). It's going to be a couple of weeks as I'm busy.

I went for Pilotsport 5. (205 x 40 R17). Visually they look good on the wheel (2 fitted). I know frostiless mentioned that they might look a little stretched on a 7" wide wheel and that's a fair point, but the ps5 has a chuncky sidewall so I've got away with it. The sidewall overhangs the tyre.
I'm looking forward to getting these on, I think this bad Karna is due to me calling the efficient groups "ditchfinders"🤣 - Joke.

Cheers

AT999 you did well going up half a J to 7inch. Good decision. The 205 needs a 7J rim to keep the contact-patch 100% central to stop overlap.👋
