hi martin. have you thought of poping some 205 45s on the alloys i am sure it will give you a nicer feel & a good diamiter too . cheers. D

[robreg5]

If 205 45 profile tyres where fitted would it eliminate the rubbing/fouling of the tyre and improve the handling, without need for spacers? Am thinking of doing this myself if spacers are not required. Any help much appreciated. Cheers Robbi.

[robreg5]

Anybody?

[JG]

anybody? anybody? How about the last three pages of posts! Sometimes i dispair, unfortunately it seems to happen more and more.

[robreg5]

I have read the last 3 pages of posts and there is no difintive answer for my question. I am asking a simple question for someone who has maybe tried 205, 45, 17 tyres on rear wheels fitted to the front. Myself like many others do not want to move away from the standard look of the car by fitting aftermarket wheels. You will never be able to iraddicate understeer on 175 tyres, my car has been set up by steve (scarred stiff) and guess what, still understeers. I do not see the need for your sarcastic remark and i totally disagree with the sarcy comments posted previously. The guy who started this thread asked a simply question, like mine and neither he or myself expect stupid replys like 'turn the steering wheel less'. I have quite a wide knowledge of mechanical principles and If I am ever asked for advice, no mater how simple the question i will nevee give a stupid answer to try and make anyone look stupid!! If you think you know everything, u really know nothing!! I have no idea if rear wheels fitted to the front with 205 45 17 tyres will foul and It does not tell me in the previous 3 pages of post!, i am 95% sure understeer will be reduced and this is why I asked the question! I have a ford escort rs cosworth aswell and at the momemt I have more confidence in corners than my vxt!! The escort is a far superiour handling car than my vx in this current state, escort is 100% factory standard car!! vxt has geo change! So please dnt put silly replys trying to make me or others look like idiots.

Rob, the biggest you can go on the 5.5J front wheels is a 195/45/17. On the basis the front wheel is significantly lighter than a rear wheel and involves zero cost or spacers , that is one option.

Also, some have fitted the Kumho KU31 195/40/17 tyre to the front.

Thanx for that helpfull reply I have seen the 195 45 option for the 5.5 front wheel before but am struggeling to find a suppyler. Have been told they have stopped making them, both yoko and goodyear and I have a friend in the tyre trade. Is the 195 40 a good option. How big of a spacer will be needed to fit a rear wheel on the front with a 205 45 tyre? Cheers Rob.

Rob do a search for "Kumho" as I know some people have fitted the KU31 tyre in the 195/40x17 size

I'm currently running Goodyear F1s and just had a search of the likely suppliers (though expect them to last another year or so as they're barely worn) and it does look like you can't get anything in 195/45x17 now

there is much more choice in 195/40/17 size

[garyk220]

There are a few posts from 5 years ago ont he subject. This one here used to have photos from all angles, but most are missing now. Simon (Foxy) fitted rear wheels with 205/40x17 tyres on the front without the need for spacers. He ditched this mod a while later and fitted Speedlines and A048R tyres iirc, although he reckoned the problem was the choice of Toyo T1-R tyres rather than the wider wheel or tyre generally.

It can be done, but even then opinion on the benefits was divided. Top tip from one of the original members from Italy: jack up one side of the car and swap the front and rear tyres over as a quick way to check clearance with a rear wheel on the front. Although I'd not recommend trying it on the road with the 175s fitted on the rear as Rikcy did

This thread seems to have lost its objectivity. Going back to your original question. You have swapped your "skinny fronts" for a wider version. Have you swapped wheels, tyres or both..? I think from what you have seen me post I am trying to help.

[Paulus H]

VX220nelly appears to be using 17 inch wheels at each corner. Why not PM nelly for a run down on the results and the "how to". And nelly, I'm not normally into black wheels. But yours look great! My silver TD's are driving me mad this time of year, trying to keep all the crud from building up on them. Also TD's are the easy get out, pay your money, get the 16/17 wheels and no thought required. The Nelly spec set up adds a different option but obviously required a some planning or experimentation with hub centric sizes/suppliers. Well done for coming up with an alternative solution.

Hi m8 you need a 10 mm spacer, for the outer rim to sit in the right spot. they come longer bolts too. with the right size tyre should work out ok. but there maybe 2 - 3. more kg.s in weight though. D .

And then your rolling radius is out by -36mm and you will probably end up with less grip on the front as there will be less sidewall flex

Hi mate..
Have 225's all round with rear wheels on each corner.
Car don't tramline, feels very positive and stable compared to what it used to.
At least now the sensible questions and answers are arriving to this thread!
I'm maybe going to get a pair of 215/45's for the front and use hubcentric spacers if i still need to.
The scrub is only on full lock and isn't that bad actually.
Will pop down to sinclairs one day this week and get some advice from them and let you all know

if you can quote a reference source for where you managed to find the exact dimension of -36mm , as in the past we have tried to get details for the KU31 195/40/17

in terms of rolling circumference exact details , the standard 17" are 175/55 so rolling circumference is 1903mm according the Bridgestone datasheet ( http://www.bridgesto...oneDatabook.pdf )

Sorry i meant overall tyre diameter is -36mm. The 175/55 is 624mm and 205/40 is 588mm

After calculating this but bearing in mind i am stupid..

175/55/17:
Rolling radius 196.13cm
Diameter 62.43cm
Sidewall height 9.63cm

195/40/17:
Rolling radius 184.66cm
Diameter 58.78cm
Sidewall height 7.80cm

As the speed sensor is in the front hub the speedo will be approx 4mph @60mph

speed sensor is in the nearside rear hub , so not change to mileage or speedo

unfortunately any tyres sizes eg. 195/40/17 are just a rough guide and won't be in any way exact or comparable. For instance the Kumho KU31 205/50/16 which several people have fitted to a 16" rim has an actual width of 214mm so very wide.
