Tyre Advice - RFT or NRFT ?

Post by Red-Eye » Tue Jun 06, 2017 1:47 pm

Hi, I'm new here so be gentle !!

I have recently purchased a 120d Coupe and loving it, but the time has come to change the tyres, I have read through the FAQ on tyres and wheels and still would like some more details and what's good and what's not.

I am currently running RFT 215/40/18 (front) and 245/35/18 (rear) and after todays drive to work I'm more inclinded to go with NRFT as I'm not liking the 'driving on ice' feel the RFT's have in the rain along with the crashing ride the sports suspension offers on B roads. I have read that it's possible to go up a size, and reduce the tyre costs if I go with 225/40/18 (front) & 255/35/18 (rear) as there are a more common sizes. Is this correct, am ok going up a size without any issues with suspension rub on a sports suspension ?

I have been looking at getting Michelin Pilot Sport 4's front and rear as have them on my wife's car and feel good to drive in both wet and dry, still unsure on wear yet though as they are only a few thousand miles old. What NRFT would people recommend ?

Any info on this subject would be much appreciated.

Cheers Red Eye

Welcome.

Excellent decision firstly to go NRFT, I changed from RFT and can honestly say it has transformed the car like no other upgrade/addition/modification I've done.

I was lucky enough to get hold of a brand new set of Michelin pilot super sports for £300!!! that are just amazing. But they are my only tyre so can't comment on other types/makes.

However, the PS4 have had good reviews as have the conti sport contact 5 and the Goodyear eagle F1 asymmetric 3 and Pirelli P zero. They all have small plus and minuses but if you can get 225/40 and 245/35 in any of those tyres I'd go for the Michelins. But if cost is an issue than any of the above would be a worthy replacement for the RFT.

There are other esteemed members here that I'd listen to but Red 5 has used most tyres mentioned above and is always happy to impart his extensive knowledge and opinion on this matter.

Although not sure he's used the new PS3, PS4 or rhe Asymm 3's

I have the PS4 on my E91, good tyres and would certainly recommend them.

And yes to NRFT, so much better than RFT. Just make sure you do all 4 tyres and get a gel kit as well.

Switched from RFT to NRFT, Pirelli standards to MPS4S. They are brilliant !

Yes, definitely ditch the Runcraps.

I'm on Goodyear Asym 3's currently which are a wonderful all-weather road tyre. I think I'm going to try PS4's next time.

Don't forget to order XL's, which means a load index of at least 92.

Everyone runs 225/40/18 92Y on the front.

On the back you have a few choices, 245/35/18 92Y and 255/35/18 94Y are the most common.

What that man said

I'm running VMR v710 18" 8.5J ET45 on the front with MPSS 225/40/18

9.5J ET50 245/35 on the rear

Fitment is perfect IMO

And grip is insane in dry conditions.

Do I need to run spacers if i go with a bigger tyre ? I'm currently running BMW 313 rims with 7.5x18 ET 49 on the front & 8.5x18 ET 52 on the rear.
The MPS4 are currently £105 each for the fronts and £149 for the rears at Kwik-fit for the bigger sizes, not a bad price I thought ?

I'm probably going to purchase a set of the Goodyear eagle F1 asymmetric 3 from the reviews I have read - (currently on RF)

quick question for the rears, as there is a choice between
245/35/18 y (92)
255/35/18 y (94)

the price is the same, so what would I notice in ride difference if any... between 245 and 255 ?

255/35 is a slightly better diameter match to the fronts, slightly more grip, and slightly more rim protection.

You won't get much below a 35 profile, so nothing wider is going to match perfectly.

275/35/18 = +2.1%, which is just about acceptable (14mm bigger on diameter).
