Best tire/wheel combo for a fun daily driver

Hilldescentcontrol · 10-27-2022, 04:19 AM

Hi all! Just got my self a 2015 116i with m-sport package. Great little car, but I cant help my self to laugh at the 245 section rear tires... It has 136hp for gods sake. And since its in need off new summer tires for next season I´m thinking of going with something lighter and more economical. I´ve tried looking at forums, where I find that people like to run 245 squared, but thats mostly for trackdays, which i won´t use this car for.

Should I go for a squared setup or staggered? I´d most probably go with 17" wheels. Is any one running 205, 215 or 225 squared? 225 in the rear and 215 fronts? Problems with understeer with narrow front tires?
Loved the chassi balance I had in my Mk8 Fiesta ST, 205 squared, but off cource thats a completely different layout. I like my cars playful but not unstable.

Spend your money on a remap first.

You will have noticed how it goes flat by 4000tpm and there's no point in revving it higher.
That changes big time with a remap.

I used the MHD app, stage 1 map and their wifi obd interface on my 2014 116i Sport.

https://mhdtuning.com/

Now I have up to 200bhp and 45+mpg. It was 136 and now pleasingly quick.

It keeps pulling and pulling to over 6500rpm and the boost pressure has risen from a lowly 10psi to 17psi.

If it still has runflats, get rid asap.

I have the original size Eagle F1s and there is no problem with understeer or rear grip (on damp roads of course, you can slide the rear should you wish to.)
It rode and handled poorly with run flat Potenzas.

MHD is on the list. I still find 245s in the rear to be unnecessarily, but I could be wrong.

Mine is a Sport, not M- Sport so has 225/45/17s all round which are good enough and probably better than wider on wet roads.

Ride quality, fuel efficiency and noise of the Eagle F1s are all very good and of course they cost much less than 245s.

Mine had quite high mileage of 85k miles so I also changed the maf and pre cat O2 sensor because the tailpipe was very sooty - looked like a 1990 Transit's and mpg was poor.

I did also change the rear silencer on the assumption that it would be clogged with soot so the aftermarket one probably also helps the performance.

I still have my factory runflat Potenza staggered set and an OEM winter runflat square set. The former makes quite a "fun daily driver" - I am not desperate for an improvement. The latter is not fun at all. I am not looking for a "happy tail" though.

So lots of support for same size all round, at least on lower power models like the 116/118i.

All from the same big enthusiast.

What about just cheaper models like not M-Sport package (were 114 no power models)?

I guess mine manages to have some wheel spin in the 3rd gear even with the wider rear tires.

Oh man, I´m so bad at that computer stuf.Thank you! Square setup seems like the way to go, now 17" or 18", 205 or 225s. Decisions...

18" are sportier: lower profile, firmer. Yet, less comfortable and more damage prone on faulty surfaces. 205 are available on 17" only (Y spoke 380 style).

Narrow tyres are good on slippery surfaces (winter) and are more economical (less rolling and aerodynamic resistance, cheaper).

I have 225/45/17 and have no complaints. (if you do the MHD remap 205s might be too small, especially on the rear)

(the lower unsprung weight is slightly better for handling and 45series give better ride.)

I might fit 205/55/17 winter tyres if I need them them winter. I have the old wheels for these, the current ones were refurbished grey powder coated five spoke ones from ebay.
