Post subject:  Fitting wider rims and tyres

I want to fit wider tyres on my swift, like a 205/50/15

Can anyone tell me how much offset and width on the rims i will need to run this size tyre?
Would a 7inch rim be too wide?

15x6.5 et40 the most would be most I would go with

There are a few people who have gone to 7" rims with flared guards etc. I would think the biggest problem is the overall size of the 205/50/15 and it foulling the guards and inner wheel well at the front. Quite a few run 205/60/13's (including myself, squeezed on to 13x5.5 rims) and this works pretty well. Would be interested in how it goes for you.

^^^I dont have a problem flaring out the fenders but its the inside im concerned about, the wheel fouling on the inside of the wheelwell.

I thought about using some spacers but my tuner advised against it, he says it will screw up my suspension geometry.

Finding a rim with 40mm offset might be a little problem tho.

David,

Both Daniel and I have almost identical setups....15 x 6.5 rim I think Danny's offset is 40mm while mine is 42mm. The tyre size is where we are different. I am on 195/45 while he is on 205/50. We both have no rubbing, but he's on stock springs while I'm on Jamex lowering springs. My front camber settings are radical though.... -1.8^ in front but I think I'll pull it back to about -1.2^ thereabouts for daily driving.

I know the purpose your car serves in addition to being a DD, so I would say if you can get some toyo proxes T1-R in the 195 width, I'd stick with that option. I stand to be corrected by imho, any rim with an offset above 40mm is going to have trouble with a 205 width tyre.

btw, congrats on your accomplishments Sunday...heard you all geed fyahs to dem hawnda and nissan boys. I wasn't there but news in the local Zuki community travels fast. :lol:

Thanks for the advice. I need more rubber on the road, too much wheelspin. I had to take the 1st gear to 9000rpm to stay in front of those guys on the straight after the launch. If you look at the vids, my advantage was on the launch but there was so much wheelspin im losing a lot of time. Also on the exit of the top 90 degree corner i could make up some time with more grip at the front. If youlook at the video with the Ignis, he corners like a go kart.

I think the wider tyres will give me a little more grip.
Im gonna try the 205s on the 6.5s with 40mm offset. If you know anyone with a used set, let me know I would be interested.

How come Daniel on stock springs now? What did he do with his springs?

BTW, there was another GTI there, a red, with a Cultus engine. It ran really well, but he needs proper tyres.
You probably know him, he says he has three GTIs.

BTW- When you bringing your lil beast out to play?? You going to let me have all the fun all alone?

By all means, go with the wider tyres....experimenting is the only way we can all learn and go forward. The ignis sport was set up by Suzuki to out-handle pretty much anything from factory in its power to weight class so yeah, go-kart would be summing it up well.

Daniel has his lowering springs in a cardboard box sitting next to the car....he doesn't seem to have much of a desire to put them on. lol

I really don't know many of the local GTi's....including the one you described. Where was he from? The only ppl I know who had 2 or more gti's were Michael Murray and Keegan (Slayer).

My car still has some ways to go before I seriously track it, but I'm hoping to have it on the road before the end of the year. What chip are you using to get to 9000rpm? I have the Toms II but that's good to 8500only. How's your gearbox handling the 9k shifts though? And where can I get good quality CV Joints locally?

I got these Sprint Hart competition rims, theyre 15 x 6.5 with 45mm offset. They work perfect with 205 x 50 x 15 race tyres.

I should have no problems with rubbing cause i have widebody kit on it.. Probably needs to be a bit wider :drunk:

I think you fitted. 215/40/17 tyres, wider tyre will give a higher overall level of grip when compared to a narrow tyre. But make sure this is because the narrow tyre will have a longer contact patch

Flexible tire sidewalls alow a single tire size to be mounted on a rim of various widths. There is a rim width range for every tire size, but on the other side, there is a tire width range for every single rim size.
Tire widths for a wheel/rim size chart shows what tire widths fit displayed wheel/rim sizes - shows tire width range for a given rim width: minimum, ideal and maximum tire widths (e.g. for an 7" wheel/rim, following tire widths can be fitted: 195, 205, 215 or 225).


Min. Ideal Max.
Rim tire tire tire
